Collide by Bal Khabra

An ultimatum from her professor thrusts Summer Preston into an unexpected collision with hockey captain Aiden Crawford. She’s caught in a delicate balance between fulfilling her lifelong dream of becoming a sport psychologist and veering far away from this god-awful sport.

For Aiden Crawford, being the captain of the college hockey team has its perks, except when a reckless mistake by his team threatens to jeopardize their entire season. Consequently, his coach nominates him as the subject of a research paper. It’s 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 his blasé approach to life, and Aiden doesn’t understand her uptight, scheduled one. They are off to a rocky start, and provoking each other is what they do best, but defeat isn’t something either of them is willing to accept.
