The Lion, The Witch and the Wardrobe is the story that introduced the world of Narnia to our world. On its surface C.S. Lewis's 1950 novel is a children's fantasy story; but it is so much more.

It is the story of the four Pevensie children - Peter, Susan, Edmund, and Lucy, who accidentally stumbled upon Narnia, while staying at the home of elderly Professor Kirk.

Lucy was the first to venture into the old wardrobe and discover that it was a portal to another world - a magical world in which animals can talk; but this was also a dangerous world ruled by the evil White Witch, who had cast a spell on the land, ensuring that it was "always winter, but never Christmas".

Lucy returned to tell her siblings about her adventure, but she was met with skepticism. Edmund followed her through the wardrobe and discovered the truth, but he was weak and spiteful and was easily seduced by the White Queen's magic and promise of enchanted sweets. They returned later with their older siblings and learned that the lion Aslan was returning to Narnia after an absence of centuries. Aslan was held in great reverence by the Narnians and was destined to confront the White Queen and challenge her reign.

Lewis combines several different cultures in his narrative. He drew inspiration for his characters from the mythologies of the ancient Greeks, Romans, Norsemen, and other cultures and from the stories of Hans Christian Andersen. Even Father Christmas makes an appearance at one point. But the story also has many influences from Lewis's Christian faith. It is an allegory of Jesus Christ's sacrifice and resurrection to redeem the sins of others. Lewis does a remarkable job of suggesting Biblical stories without repeating or imitating those stories.

"The Lion, the Witch, and the Wardrobe" is a classic story that combines adventure, magic, family, action, religion, betrayal, forgiveness, and redemption in a very short space.

I never read this book as a child. I was in my 40s when I first experienced Narnia. Two decades later, I find it is still magical.

The Magician's Nephew was not the first book that C.S. Lewis wrote for his classic Chronicles of Narnia; but its story is first chronologically, and it often appears first in omnibus editions of the Chronicles. So, as I set out to re-read the series for the first time in 20 years, I elected to begin with this volume.

The story takes place prior to Lewis's iconic The Lion, the Witch, and the Wardrobe. A generation passes on Earth between the two novels; but a thousand years separate the two books in Narnia.

This book is the story of Digory and Polly, two children who find themselves transported to another world, tricked there by Diggory’s evil Uncle Andrew - a amateur magician of mediocre skill and dubious morals. When the children return to London, an evil witch queen from the other world follows them intent on ruling the Earth. The children work to drive the witch out of their world.

In this book, we learn answers to questions raised in later books: how Narnia came to be, why some of the animals can talk, how the White Queen came to Narnia and why she was kept from power for so long, why there is a lamp post in the middle of the woods, and why Professor Kirke was unsurprised when he learned that his wardrobe was a portal to another world.

Lewis was fond of including Christianity in his book and this story echoes many of the themes of the Book of Genesis, including representations of God, the Devil, the Creation of the universe, the first man and woman, and even a fruit tree.

You may choose to read the series in chronological order or in publication order (this was #6 of 7 written) or you may read them in any random order you wish. The Magician's Nephew is a delightful story on its own, but even more so for those familiar with the other Narnia books.

When Tom Joad came home after four years in prison, his house was empty, and his family was gone. Nearly all the families in the area were gone - driven away by the drought and by poor soil management and by the bank that took their homes.

Tom found his family at the home of his uncle. With no prospects in Oklahoma, they decided to head to California, lured by a handbill's promise of plentiful jobs. The handbill lied. They expected California to be the promised land; but it is a land of broken promises.

John Steinbeck's The Grapes of Wrath follows the Joad family across the country to California, where they face unemployment, poverty, and a system designed to keep them down.

The Joads and others like them feel helpless. They are starving and have no source of income, other than an oligarchical system of large farms that reduce wages to poverty levels. They try organizing and they are labeled Communists and beaten by police. They try helping one another, but the authorities harass them and burn their camp. They are angry but have nowhere to direct their anger. Just as the faceless bank foreclosed on their homes in Oklahoma, the faceless farms control their lives in California. There is no person to whom they can appeal or at whom they can lash out.

Steinbeck's writing is straightforward, but beautiful. He paints a very real picture of the world in which he Joads live and travel. He makes us care about an entire class of people - the working poor in this case - and about the individual characters in his story, including:

  • Pa Joad, the family patriarch, who cedes leadership to his wife.
  • Ma Joad, whose strength holds the family together.
  • Jim Casey, the ex-preacher, who has lost his faith; but finds a purpose in life after he is arrested for someone else's crime.
  • Tom Joad, who struggles to control his anger because he knows the consequences for himself and his family.

Steinbeck makes one feel the pain of oppression without ever getting preachy. Even the former preacher Casy manages to deliver his message without preaching. The endurance and resilience of the Joads and their repeated frustrations with the system makes the author's points for him. The Biblical parallels are clear, as the Joad’s exodus mirrors the trials of the one led by Moses.

This is one of the great American novels. It is a bleak story of life during the Great Depression - a story of man's inhumanity to man and of man's kindness and resilience and perseverance in the face of adversity. Sometimes the oppressed turn on one another; but more often they face greed with dignity. It is a moving story of community and family; it is a story of hope and disappointment and despair. It is a warning of concentrated power. It is a classic.

Neil Gaiman's The Sleeper and the Spindle is a short fable that combines the legends of Sleeping Beauty and Snow White.

The book is beautifully illustrated with ink drawings by Chris Riddell - mostly black and white with a few splashes of gold.

Gaiman's gift for storytelling keeps one engaged, even with a familiar story; and his imagination provides a twist at the end which turns on its head our concept of villain and victim.

Although the story is a bit dark, the length of the book and the familiar topic make it a good book for children; but I found myself captivated by the magic in the book and in the telling.

"War was always here. Before man was, war waited for him. The ultimate trade awaiting its ultimate practitioner."

In the mid-nineteenth century, the Mexican government hired John Joel Glanton and his group of mercenaries to hunt Apache warriors, who had been attacking citizens. They paid Glanton for each Apache scalp he brought them. After realizing that the government could not distinguish the origin of the scalps, the gang began a murderous rampage, killing women, children, and anyone in their path.

In 1985, Cormac McCarthy published Blood Meridian or The Evening Redness in the West - a novelization of the exploits of the Glanton Gang.

The book follows "The Kid" - a violent youth who flees Tennessee to the Texas-Mexico border and joins with Glanton's crew. The Kid participates in the gang's violence, but mostly serves as an observer to the other characters and the action of the novel.

The most intriguing character is Judge Holden, a giant hairless albino, who serves as Glanton's second in command, but is the one in control of the company. Holden is a huge character - physically and metaphorically. He is a philosopher, who believes that war is man's ultimate occupation, and he is a charismatic manipulator, who serves his own moral purposes. The Judge is a memorable villain - a pedophile and a liar and a murderer and a sadist. He may even be Satan himself and the wastelands of northern Mexico and the southwester US may be the Hell over which he reigns.

The Kid is left to fight for his life as well as ponder the morality of what he is a part of. He is the only gang member and one of the few characters in the novel who shows anything close to mercy or any contrition for the atrocities committed.

The story becomes more savage, brutal, and bleak as it progresses. Eventually, the violence seems inevitable, as do the consequences - both to the victims and the perpetrators.

This book does not romanticize the Old West as so many western novels do. It exposes some of the racism and destruction rationalized by a belief in Manifest Destiny. It shows the dehumanization of Blacks and Native Americans by the white conquerors and it reveals the lack of humanity by those conquerors.

Blood Meridian has no protagonist, no plot, and almost no character development. But it does have raw emotion. And it brought difficult questions to my mind: Is man fundamentally good? Does war have a place in society? Who is the sinner in a conflict where everyone is committing atrocities?

If you are looking for a Western story of cowboys and Indians and heroes and bad guys, this is not for you. If you are looking for a grim statement on man's nature, brace yourself and dive into this novel.
