This book is kind of sort of a prequel to the first in the series, since it starts long before Love Can't Conquer, but it's about Jeffrey's friend Nevin Ng and his boyfriend Colin, who Nevin mentioned a couple of times in the first book but who we never met. Now we see how they met and slowly fell in love.
Oh, so slowly. Nevin's a complex character with many walls built around him after a lifetime spent in foster care and for once, we're given a story that gives a more realistic portrayal of how such a character might fall in love. And it's not over a couple of nights. While Nevin becomes interested in Colin fairly quickly, it takes much longer for trust and love to develop. It also takes a lot of patience on Colin's part.
Colin didn't have the lonely life that Nevin did growing up, but he did have to grow up with health issues and the uncertainty of life that can bring. He's always had to be careful, and never had much excitement. So when he meets Nevin, he sees this as his chance to have a wild fling, and hopefully maybe something more if he can keep Nevin from bolting.
I'm not sure why, since I really liked Colin and Nevin, but I never really got them as a couple. It's no fault of the book, but they just never quite clicked for me and I can't even point to any one particular thing to explain why their chemistry was off. Maybe it was simply a matter of I'd rather be reading about Jeremy and Qay again. It might be better actually to read this one first, though it would spoil the ending of the first book so I'm not sure I can actually recommend that either. Maybe start this one until they start talking about Thanksgiving dinner, and then go back and read the first one to the end, then come back and finish this one?
There's also another quasi-mystery here that doesn't get a lot of focus despite Nevin being a detective - hence why I didn't use the mystery tag - but is sort of bubbling in the background until the very end.
