Why "Everyone Dies"?

Years ago I co-wrote a book where the protagonist died at the end. We resurrected him in the second book of the series. I have always wondered if that was a mistake. That the first book should have been the end of it. The protagonist was willing to pay the ultimate price to save his friends, but in the end did he actually pay it if he came back?

Thus came the idea for "Everyone Dies". The expectation from the beginning is death. The deaths of all the characters is set in stone. As much as I have gotten attached to some of the characters, by the end of the book they all have to die.
