Rachel Klein never meant to kiss her creative writing professor, but with his long eyelashes, his silky hair, and the sad life he laid bare on Twitter, she does, and the kiss is very nice. Zahid Azzam never planned to become a houseguest in his student’s sprawling Connecticut home, but with the sparkling swimming pool, the endless supply of Whole Foods strawberries, and Rachel’s beautiful mother, he does, and the home is very nice. Becca Klein never thought she’d have a love affair so soon after her divorce, but when her daughter’s professor walks into her home, bringing with him a standard poodle named Princess, she does, and the affair is … a very bad idea.
