My favorite MC romance!
Format: Paperback
I can’t say enough good things about this book and the series! Emma Slate is an amazing dialogue writer. The story line gets your attention right away and holds throughout the whole book.

Fun and good read!
Format: Paperback
I finished this book faster than I’d like to admit but it was a good read by the pool! It captured me from the beginning and there were very short to almost no dull or boring moments. It was slightly predictable but if you’ve seen other MC shows or read other MC books, you know they’re all similar. Overall would recommend!
