Yowza, what a quick read these books are.
OK, I won't be too wordy here. We pick up a few months after the Christmas part, a week after which Kelsey found Courtney, Evan's fiancé in bed with Todd, her husband.
Evan invites Kelsey to a week in Hawaii, what was supposed to be his and Courtney's honeymoon and she accepts. In Hawaii they find their attraction to one another, and act on it, only to be snapped back to reality with a phone call from Todd's mother.
The story is very VERY predictable, but sweet and flowing. Cute, light read.
