3.5 stars. There was parts of this book I really liked and other parts that were simply ok. I really liked the character of Tyler but Mark and Alistair didn't always click with me. I wasn't a fan of their open relationship, but yet, it helped to show that they both realized that despite their love and commitment to each other; they both recognized they were missing something being too much alike. I thought the writing was solid and showed a different perspective on how a m/m/m relationship could work.
