Book club suggestions with happy ending?

I am hosting book club in March, which also means I am to select the book for that month. The problem is, most of the things I read seem to be kind of deep and don’t always end on a pleasant note.

I don’t want fluff; however, there are some members who will not read anything that takes a huge amount of effort or is so long that it looks intimidating. I suppose I am looking for something in between.

Obviously, it is more of a social book club than an intellectual. We are all moms and, so far, anything with harm coming to a child has not been well-received.
