Bam reviewed this and I reserved it because it sounded like a really good read. And it was!
Carolyn is the type of romance heroine I like - she's 31, she's not too annoyingly passive, she's had orgasms and she's not a virgin. She does have a Haunted Past and mysterious origins, but in a totally believable foster child way. Carolyn was fostered by the wealthy McDowell family. They treat her like a servant. But she's stuck there for the moment, because the woman who raised her is dying.
Surprise! Her long-lost son shows up, after 18 years on the lam. But is he really who he says he is? And if so, is this Carolyn's chance to fulfill the mother of all adolescent crushes?
Snarky rich people, Martha's Vineyard, mistaken identity, violence, etc. The plot moves along nicely, and Carolyn and Alex's relationship is engaging without being over-the-top. Great fun.
