Just in Case

Just in Case
By: Meg Rosoff

Outer back cover: The day David Chase saves his brother's life, his whole world changes. Suddenly every moment is fizzing with what ifs, and it's up to David to outwit fate. Or try to.
He changes his name and the way he looks. He leaves home and finds himself caught up in a series of strange and extraordinary misadventures. He even falls in love. 
But is David really in control of his life? And if he isn't - who is?

Interesting book, it's quite well written and points out the dangers of focusing on the what ifs, even if it is pushed to extremes.

It's a kind of depressing book because of the mood of the main character. I didn't really like David but he was interesting.... I did like his brother Charlie though. The insight Rosoff gave the toddler was quite cool and funny.
