No Girls Allowed

Who doesn’t want girls to play hockey?
As one of two girls on her hockey team, Eva is upset when someone posts a sign on the locker room door that says, “No Girls Allowed!” But she tries to pretend it didn’t happen.
More signs show up, and Eva must face the fact that someone doesn’t want her and her friend Josie on the team.
When all signs point to the culprit being a member of her own team, will Eva stand up for herself or continue to brush it aside?
And can her dogs Buddy and Panda figure out who is posting the signs before it tears the team apart?
