Realms of Light (The Colliding Line Book 2)

From the Ashes, Spring Will Rise
 
On the run from the brutal Sage and his army of Legions and Cormorants, seventeen-year-old Cera Marlowe knows the only place strong enough to protect her is the Alliance Council Estate.
 
Cera’s introduction to the Estate is far from welcoming. As a Blight, her dueling powers of light and darkness make her a half-breed threat to the Alliance’s sacred powers. Cera’s ability to decipher hidden messages in classical artwork buys her shelter temporarily, but the clock is ticking as she’s faced with a daunting choice that could cost her everything.
