Lisa, Bright and Dark — John Neufeld

"I think I'm going crazy."

Lisa Shilling is sixteen, smart, and attractive, with a great boyfriend. There's only one problem: She's losing her mind. Some days are "light," and everything is normal. Other days, she hides deep within herself, where nothing can reach her. Even worse, the grown-ups in her life have let her down. Her teachers are afraid to interfere, and her parents deny there is anything wrong with her. Only Lisa's three best friends are there for her. But can their hope, love, and plan for "therapy" save Lisa from sinking further into the depths of her troubled mind?

Hailed as a "work of art" by The New York Times, this bestselling classic turns a deft touch and understanding spirit to the story of a teenage girl's descent into madness -- and the three friends who are determined to walk with her where adults fear to tread.
