Collide (Off the Ice, #1) by Bal Khabra
“An ultimatum from her professor thrusts Summer Preston into an unexpected collision with hockey captain Aiden Crawford. She finds herself delicately poised between pursuing her lifelong dream of becoming a sports psychologist and straying far from this despised sport.
As the captain of the college hockey team, Aiden Crawford enjoys certain privileges, except when a thoughtless error by his team threatens to jeopardize their entire season. Consequently, his coach selects him as the subject of a research paper. It’s the last thing he wants, especially when the girl leading the project appears capable of using his skates as weapons.
Summer can’t tolerate his carefree approach to life, and Aiden can’t fathom her rigid, scheduled one. They get off to a rocky start, and their specialty seems to be provoking each other, but neither is willing to accept defeat.”
