Take what you thought was "rock and roll excess," double it, and you still would not be anywhere near the dizzying life of Ozzy Osbourne. Born into a life so poor that the entire family slept in one room, music was his salvation, and his band Black Sabbath went on to change the musical landscape forever. The inevitable sex and drugs came along with along with the rock and roll lifestyle, and Ozzy soon fell into an epic relationship with booze and chemicals.

The stories of Ozzy's days on the road are now those of legend—biting the head off of a live bat, the tragic plane crash that took the life of his best friend and writing partner—but few know about the real heartbreak he suffered during those days of hard living. I AM OZZY (Grand Central Publishing Hardcover; $26.99; January 25, 2010) is the heavy metal pioneer's unbelievable story told, for the first time, in Ozzy's hilarious, witty, and inimitable voice. In the end it was love that saved him: the love of his wife Sharon and kids Aimee, Kelly, and Jack.
