Faebled (Paperback) by Colleen Rochelle, Jasmine Nicole

All Ava Spiaggia knew was life at the lonely Glovemont orphanage, where she spent most of her time, friendless and alone. All of that is about to change when she meets a mysterious boy with a shocking revelation; Ava is not human, but a powerful water faerie. He soon convinces her to come away with him to a place she never even dreamed existed. There she finds not only friends, adventure, and a world full of beautiful mystery, but her destiny has been set in motion. From faerie elders and spirits with dark secrets to mischievous faerie princes and medieval balls, Ava's entire view of the world has been turned inside out. She finds that she is one of two keys to saving the faerie realm, and lands herself amidst a faerie revolution caused by the carelessness of humans. Now she must decipher between who to trust in this seemingly perfect world, making a few mistakes along the way. Soon, she realizes that even though the grass is greener in the faerie realm, they are much more like the humans than they are willing to admit.
