While this is part of an extended series, it can be fully enjoyed on its own. 
 Austin and Vinnie have been best friends, and casual sex partners, for seven years. They are juniors at college and both on the crew team, Vinnie as a rower and Austin as coxswain. Austin is an art student who longs for a serious relationship with Vinnie. It seems that Vinnie's only interested in having a physical relationship with Austin after he's settled all of his own issues with school--and then he gets drunk and tries to hook-up with Austin. It's a bit demoralizing for Austin who tells this story. 
 While at a live drawing night Austin finds himself to be unexpectedly attracted to the nude model, Sean. Sean makes no pretense of not being interested. He's been following Austin for while--hoping to gain his attention. Austin finds this to be remarkable, and exciting. Such a contrast to closed-off and unavailable Vinnie. While the attraction is intense, Austin is quick to let Sean know that he's not exactly looking for anything serious. Austin has this heartbreaking-misplaced loyalty to his bestie, Vinnie. He doesn't want to give up on their friendship, and arrangement, especially for someone new who may not stick around. As Austin and Sean spend more and more time together, however, Austin finds exactly what he'd always needed from a partner. His affection for Vinnie remains, though his interest in continuing their sexual relationship has totally waned. Mostly because he and Sean are rather insatiable for each other. 
 What started as a casual affair becomes the most important thing--and Austin learns to value himself more because he sees that he's worthy of great love. I really dug this book. It's so sweet and totally sexy and I loved how Austin and Vinnie worked things out, despite the strain of Austin's new love. Sean is a rock, in more than one way, and he's so lovely and passionate and compassionate. I had a couple *squee* moments on Austin's behalf.
