Realms of Light by Sandra Fernandez Rhoads, in this second book from the Colliding Line Series, seventeen-year-old Cera Marlowe is on the run from the brutal Sage and his army of Legions and Cormorants, knowing the Alliance Council Estate is the only place strong enough to protect her. Cera's introduction to the Estate is far from welcoming, as being a Blight, her dueling powers of light and darkness make her a half-breed threat to the Alliance and it's sacred powers. Fortunately, 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. Hardcover, 336 pages.
