Spoiler free description: Minn is an average looking, man-hating, logical actuary. Cal is a gorgeous womanizer runs from commitment. When Minn's ex bets Cal that he can't bed Minn (because, of course, since Minn wouldn't sleep with her ex in 2 months, she must be frigid...) and Minn overhears the bet, hilarity ensues
The best: Really well written! Just about the best sexual tension I've ever read. And laughter abounds in the secondary characters as well as Cal and Minn. Awesome.
The worst: Cal's ex. Cal and Minn's parents. Cold, almost non-human.
Would you recommend this book? Absolutely!!! To anyone
