Her sister has been taken, and the only boy she's ever loved has disappeared. To get them back, she'll have to use the magic she's always feared.

Liora has shone from within ever since a star collided with her house when she was a child. Since that day, she has spent her life indoors, only venturing out on the brightest days when her magic can't be detected. For discovery could mean falling prey to the king's warlock, Darius, who uses mages' magic to grow his own power.

But when her worst nightmare comes to pass, and Darius discovers her, she's not the one taken. Instead, he demands that her younger sister return to the capital with him to work under his watchful eye. To make matters worse, Evran, Liora's childhood friend and the only one who knows her secret, goes missing following Darius's visit, leaving Liora with no one to turn to.

To find Evran and to save her sister, Liora must embrace the power she has always feared. But the greatest danger she'll face is yet to come, for Darius has plans in motion that will cause the world to fall into chaos — and Liora and Evran may be the only ones who can stop him.
