Collide

A USA TODAY BESTSELLER!She's an honors student with ambitious graduate school plans and he's a jock with only hockey on his mind, but once their worlds collide, their connection is hot enough to melt an ice rink. An ultimatum from Summer Preston's thesis advisor thrusts her into an unexpected collision with the hockey team's captain, Aiden Crawford. She's caught between conflicting desires of fulfilling her lifelong dream of becoming a sport psychologist and staying as far away as possible from the god-awful sport.
And once she meets Aiden-well, let's just say he confirms all her worst assumptions about hockey players. Being the captain of the college hockey team has its perks, except when a reckless mistake by Aiden's team threatens to jeopardize their entire season. As punishment, Aiden's coach nominates him as the subject of a student research project. Participating is the last thing he wants to do, especially since the girl leading the project looks like she could wield his skates as a weapon.
Summer can't stand Aiden's blasé approach to life, and Aiden doesn't understand why she's twenty years old with a twenty-five-year plan. But their bickering soon turns to bantering-and once they let their guards down, there's nothing to check their feelings.
