What is the title of this book?

[Erin]

I saw an ad for this book on the side of facebook & the ad went away before I looked up the book. I remember that it had butterfly in the title and the cover of the book was blue with a green hand on it that was missing the pinky. If someone could tell me the name of the book I would really appreciate it.

The Last of the Butterflies by BL Baker
"The Last of the Butterflies is a book about love, loss, hope, and the complexity of forgiveness. A journey of self discovery that asks the question; should you continue to love someone once you've discovered the monster within them."
