Don't Call Me Sidekick! Book 1: The Contract by Brenda Hickey

Enter Hazelton Academy, where an unlikely duo must pull together to battle the monsters not just outside their school walls, but within. ?Kailee Hazelton has a lot to live up to, and it's off to a bad start. After being publicly rejected in front of the whole school by her partner, a magical Neysa creature named Ary, she finds herself at odds with her family and unsure of her dream of joining the Phantom Guard. ?But hot-headed Ary is nobody's sidekick, and she's got good reason for bucking back against the system - one of her Neysa friends has mysteriously vanished and no one seems to want to do anything about it. ?But trouble isn't just brewing inside the school walls. A Phantom attack on the city catches them unprepared, and they must put their differences aside to face the threat.
