Book 1?
Okay, this is weird. Book 2 came out before Book 1. Book 1 is chronologically first, but some things are explained better in Book 2. So, which one should you read first?
I read Book 2 first and absolutely do not regret it, but it probably doesn't matter that much. Just know Book 2 has more world building, if you didn't understand something in this book. If you read Book 2 first, it does have some spoilers.
The conflict here is mostly that Chase isn't sure he wants a guy, let alone a vampire. There's also a little bit of action because of how rare and valuable mates are. The romance is sweet and sexy, and there are some funny or ridiculous moments, but it isn't as funny as Book 2.
The world building leaves something to be desired for me, and I don't prefer this sort of power imbalance in a relationship, but I'm also not a fan of vampires, so if you are, you'll probably love this story.
