A breath of optimism

What I remember of Ca is optimism that underlies the story.
Faced with the unspeakable, a group of friends refused to close his eyes. Unable to resist her that their friendship and determination, they will overcome and grow emerge.
One of the few books that had me worried. But also one of those that has been struggling to which we regret that it is over.

A horror book, maybe ... But a lesson of courage first.
