I have loved this series so far, so I am shocked that this one didn't really do it for me. Basically, this book was a loosely strung together conglomeration of all of the sub-stories in this series. We get the continuing development of Kaleb's newish marriage to Zoey (book 1), Zane romance with V (book 2), and Travis's "monogamous menage" with Gage and Kylie (book 3). These continuation stories include a lot of gratuitous sex. We also get a glimpse of Ethan's forthcoming book which is going to apparently be a m/m love triangle between him Beau and Blake, a peek at the love life of the twins, Brayden and Brendon, and their sharing of all things, including Jessie or not, and more of Sawyer's hinted at relationship with Kennedy. I am still looking forward to the full books for each of these brothers and even though this book wasn't the best, it will probably be a necessary read before continuing on in the series.
