Blue Violet

Ellie Aubrey is a centuries-old gypsy princess whose extraordinary abilities once inspired her Roma ancestors' fairytales (or nightmares). Along with her twin-brother, Griffin, Ellie has spent most of her life hiding from the Vyusher, a rival tribe who destroyed their entire powerful family. But after a mysterious dream, Ellie risks discovery in order to find and watch over the Jenners, another group of similarly gifted people. She refuses to let them suffer the same fate.
 
Alex Jenner has come home to protect his family. His adopted mother can sense danger coming, but not who or when. Suspicious of the new girl in town, Alex challenges Ellie in ways that will spark one of two possible outcomes: they'll spontaneously combust, or she'll lose control of the one power she's fought so hard to contain.
 
When the Vyusher once again threaten everything she holds dear, Ellie will have to face her worst fear, and Alex will have to face an impossible decision. In this fairytale, the dragon that the prince must slay is also the princess who holds his heart.
