Amethyst & Onyx, The Binding Stones

Magic runs thicker than blood. With a single note on her locker that reads, "We See You," everything changes for Hazel Sayers. She and her siblings have tried to smother the rumors that their mother was a witch, but when a mysterious fire at a nearby high school throws her into the company of someone from her past, the truth is undeniable; she and her siblings have inherited their mother's power, and there's someone out there that is willing to do anything to take it from them.
