Here is A Lion Among Men by Gregory Maguire, volume three in The Wicked Years.
Return to a darker Oz with Gregory Maguire. In A Lion Among Men, the third volume in Maguire’s acclaimed, New York Times bestselling series The Wicked Years, a fuller, more complex Cowardly Lion is brought to life and gets to tell his remarkable tale. It is a story of oppression and fear in a world gone mad with war fever—of Munchkins, Wizards, and Wicked Witches—and especially of a gentle soul and determined survivor who is truly A Lion Among Men.
While civil war looms in Oz, Brrr—the Cowardly Lion—surrenders the story of his life to a tetchy oracle named Yackle. Abandoned as a cub, Brrr's path from infancy in the Great Gillikan Forest is no Yellow Brick Road. Seeking to redress an early mistake, he trudges through a swamp of ghosts, becomes implicated in a massacre of trolls, falls in love with a forbidding Cat princess, and avoids a jail sentence by agreeing to serve as a lackey to the war-mongering Emperor of Oz.
A portrait of a would-be survivor and a panoramic glimpse of a world gone shrill with war fever, Gregory Maguire's A Lion Among Men is written with the sympathy and power that have made his books contemporary classics.
