The council of shadows

"Adrian Brézé defied his own dark heritage as a near-purebred Shadowspawn for years, until his power-hungry sister Adrienne kidnapped his human lover Ellen. Now, Adrienne is dead, and the Council of Shadows is gathering its strength. To stop the Council from launching an apocalypse, Adrian and Ellen must ally with the Brotherhood, a resistance group dedicated to breaking the Council's hold on humankind-- by any means necessary"--Jacket p.
