This is the third book in the supernatural sisters, and we finally get to see the nerdy book, loving youngest sister, who is a professor get together with the guardian angel. We know she’s a professor over at Harvard and she really wants to study having apprenticeships between human and supernatural societies to create a better understanding of both societies. However, things aren’t going so well, and she needs to move into a new apartment. Our guardian angel gives her space in his place. The problem is everybody knows these two have a hots for each other and just can’t talk about it. And of course, moving in together means they become involved. The downside is that Box is given Olive as an official duty to guard. He tries to tell his boss we’ve been friends we live together, but they’re like do this or you’re fired. You see Olive has decided she’s going to do 10 things that are scary. She assigned her students this project but thinks if I’m going to give it to them why don’t I do it myself. This book, of course involves sex, singing, doing crazy unexpected things, and things that scare you. This book is just like the others. It’s cozy, it’s a little spicy, maybe a little more than spicy… they get into piercings. But it is fun. I really like this series and I hope it isn’t over because I really want the book about their succubus friend.
