I think I liked this one even better than Backup Boyfriend. 
 It's hard to talk about without giving anything away, but I'll try. I started off thinking I'd need Memphis to do some serious groveling for leaving Tyler as he did, but then when we learned why (the first why then the full-out real why - which, ouch, but totally understandable given the circumstances) I was able to see his POV. He also came across as pretty cocky and too sure of himself at first, but again, once you know what he's been dealing with his attitude becomes understandable. 
 Tyler tries so hard to not feel (with his history (view spoiler)[the way his bio mother put him up for adoption had to leave scars then for Memphis to do pretty much the same thing (hide spoiler)] it's understandable), since we're in his head part of the time we know that, but I'm glad Memphis tries (and eventually succeeds) in being able to read the "new" Tyler. I like that the ex-wife isn't some Evil Interfering Woman. I like that Tyler and Dylan make peace of sorts. 
 As for the last little bombshell obstacle... I can't really say much without saying TOO much, but I was starting to sweat whether we were going to get a HEA after all. There really is no way to talk about the ending without giving it away, so I'll just say it was good without being too good to be true. Also I'm really looking forward to Noah's story (view spoiler)[ with Ky (hide spoiler)]. 
 Overall very enjoyable. Makes me glad I haunted Amazon until they finally posted it. ;-)
