Book excerpt: Every night Babe dreams of a boy she’s never met before named Zat. But Zat is no ordinary daydream. He’s actually a human from the distant future, who has travelled back in time to be with Babe in the only way that he can be—in her dreams. But the dreams leave Babe more and more tired and pained each morning. Zat is determined to help her, even if it means never sharing dreams with her again.
