If you had asked me earlier this year if I was a fan of MC club romance books, I would have answered no. However, I've dipped my toes into those worlds this year, and I have to say: my mind is changed! I read this series out of order and started with this book based on a recommendation from a friend. Welcome to the Dark Side is an age-gap romance (19 years), and is a forbidden romance between LouLou and Zeus. LouLou is quite young, however, I love the way that Zeus treats her. He does not come off as a predator, even though LouLou is quite young. Also, LouLou has an old soul for someone her age. Age gaps can go really, really badly, but this book just worked for me. I rated this 4.5 stars, and rounded up for Goodreads.
