Misfits Series by Niall Teasdale

Once upon a time, a handsome prince met a beautiful princess and they fell in love. Everyone in the land of Draconia rejoiced, the prince and princess were married, they had a daughter who was pretty and wise, and they all lived happily ever after. Yeah, like that’s ever going to happen…

There’s a new student at the Celestina School of Magic; a girl with a secret only. And it seems like only the misfits are willing to help her resolve it. Then a cryptic message from beyond the funeral pyre takes the girls to Tangleroots, a dense, dark, and possibly cursed forest, where a witch may have answers to who Krystal Ward really is, and someone seems determined that none of the misfits make it out alive.
