The grand scheme : a novel / Kathy Herman.

Enhanced descriptions from Syndetics:

Envy is a deadly poison. Faith is the antidote.

Things couldn't be better for Rue Kessler. He just married the mother of his eight-year-old son, Montana, and finally has the family he's always dreamed of. Not only that, his father-in-law hired him to be the new construction supervisor on a big condo project. He's been sober for eighteen months. He's finally plugged in at church. And he's building his wife Ivy the house she's always dreamed of. Life is good.

Then with no warning, Rue and his wife and son become the target of someone's cruel and frightening attacks. What reason would anyone have to dash their hopes and dreams? What will it take to stop it? What defense is there against an enemy he can't see?

While Rue's head is still reeling, a man on his work crew is found half dead in Tanner Canyon. Are the attacks related? Is someone trying to put a stop to the condo project? Or is something more sinister afoot-something that will take all the faith he's got to confront?
