You might try Philip Pullman's "His Dark Materials" trilogy. (The first book, "The Golden Compass," just came out as a movie, but there's a lot more in the books!)
The lead character, Lyra, is amazing...and her family is about as dysfunctional as it gets. She's from an alternate version of our world, but the male lead, Will, who shows up in the second book, is from our world, trying to cope with a schizophrenic mother. There's a whole lot in there that survivors can respond to.
One plot element is a plan to assassinate God.
