Reluctant by Allyson Lindt

Jodie’s got the perfect life plan—finish her graduate work at Stanford, land an internship at the most advanced transplant-research firm in the country, and become an innovator in the same field. There’s no room in her life for the random variable and a one-night stand with a guy who has no interest in sharing the responsibility of a child. The only person she can turn to is the stepbrother who made her life a living hell in high school.

Logan is intelligent, sexy-as-hell, and asinine to a fault. He’s got his kind moments, but they tend to end with him and Jodie screaming at each other… or screaming each other’s names, after they lose all their clothes. If they can’t stop the fighting-mixed-with-passion long enough to find a solution for the pending new arrival in Jodie’s life, they risk three futures.
