Perfect Formation Book Review and Recommendation Taryn, Richard and Caleb sizzle in this book that takes the traditional relationship and flips it off the mountain. I first downloaded this book on a BookBub deal whim. MMF can be sexy. I was expecting a tale of sex with a little plot on the edges. The relationship has depth. The characters are realistic. We meet the characters families for goodness sake. Like, this isn't just a drunken night or a sex club kind of fantasy exploration. Or, as some books do, a sexual relationship only. Nope, these guys fall in love. It's the good kind of MMF, meaning the men are bisexual. It's always a little off to me when the men don't touch each other at all. The chemistry between Richard and Caleb works even without Taryn in the room. Perfect Formation is a part of a series, but each book is a true stand alone. KB Alan rocks the sex scenes. And reminds us that Love Is Love Is Love stands for all kinds of relationships.
