The Serpent in Heaven (Gunnie Rose; Center Point Large Print, 4)

Felicia, Lizbeth Rose's half-sister and a student at the Grigori Rasputin school in San Diego -- capital of the Holy Russian Empire -- is caught between her own secrets and powerful family struggles. As a granddaughter of Rasputin, she provides an essential service to the hemophiliac Tsar Alexei, providing him the blood transfusions that keep him alive. Felicia is treated like a nonentity at the bedside of the tsar, and at the school she's seen as a charity case with no magical ability. But when Felicia is snatched outside the school, the facts of her heritage begin to surface.
