Dangerous Play by Emma Kress 

Zoe Alamandar has one goal: win the State Field Hockey Championships and earn a scholarship that will get her the hell out of Central New York. She and her co-captain Ava Cervantes have assembled a fierce team of dedicated girls who will work hard and play by the rules. But after Zoe is sexually assaulted at a party, she finds a new goal: make sure no girl feels unsafe again. Zoe and her teammates decide to stop playing by the rules and take justice into their own hands. Soon, their suburban town has a team of superheroes meting out punishments, but one night of vigilantism may cost Zoe her team, her scholarship, and her future.
