Caroline — Rachel Billings

Wearing nothing but a smile and his best friend's shirt, Caroline Freeman is the last person Matthew Churchill expects to find in his kitchen on a Saturday morning. She was fifteen last he saw her, a sweet, unforgettable summertime crush. Hell, if he'd known that lovely Caroline was the woman Jackson Roberts has been wooing, Jack would never have gotten her to his bed last night. Jack and Matt are as close as brothers. For five years, they've shared a house and the trials of grad school. When they both want the same woman, Jack suggests they continue sharing. Professor Daniel Ryan isn't blind to the heat in their relationship. He wants to be a part of it and suspects Caro wants it, too, despite her denials. The day after Matt and Jack graduate, Daniel has what he wants. He's got them in his home, and a ring-three bands united by one whopping big stone-on Caroline's finger.
