To start: this is book 2 in a series yet I have not yet read book 1, so I consider this able to be a standalone.
I loved this book. Sebastian is a very well developed character with some dark demons from his past. Marisa has a past as well, to me not as bad but she still has to deal with her drunk father. This books gives us good backgrounds into these characters as well as many twists and turns throughout the book. I could not put it down.
Of course we get a HEA at the end of the book, but watching their stories develop separately and together makes for a great read and helps you root for them even more!
