Mark Manson is the MAN, son! I've been following his blog for ages and no one writes as clearly and level-headed about complex interpersonal topics as he does. Haven't checked this book out but I think it's similar to one of his blog posts that BLEW up. Maybe it's how he got the idea for the book :)
