Assumed it was a COVID novel: nope, published in 2010!
A pandemic orphan, Cole is fostered by a fundamentalist pastor & his wife. They are good, kind people but their values and culture are poles apart from those of his liberal atheist parents. What's a boy to do when he loves them both?
The stuff about rapture children made me deeply uneasy.
Don't know why some of the plot points were introduced. Not sure how I feel about such a low key ending..
