If we had official half star ratings I might be tempted to bump this up, but since we don't I decided to stick with 4 stars because despite my enjoyment of it, this book did have its flaws.
There were some moments throughout where certain things approached "rainbows and lollipops" status - Richard was oh so rational and understanding and always wanted to talk everything out and deal with everything in such a healthy way. And Matthew was so cute and bubbly and adorable and puppylike. It never got out of hand but it skirted the line a few times. I also felt like there might have been a little too much sex. It was not a porn-without-plot, but I could have done with 2-3 (or 5) fewer sex scenes. Not that the scenes weren't good. They were. It just seemed like they were a little too quick to turn to sex as an answer for everything.
This book also felt very long. Which wasn't a bad thing. For most of it, I would look at the page count and be glad I still had so much left to read because I was enjoying it so much. But toward the last third or so I felt like things could have moved a little more quickly.
But for the most part this was a really great m/m/m relationship book. Readers like me who are fascinated by the dynamic of a committed threesome, and like to read these books to see how three people can balance a relationship, will really like this one. I'll definitely be looking for more from this author in the future.
