The Serpent in Heaven by Charlaine Harris is the fourth book in the Gunnie Rose alternate history, western, fantasy series - this one focuses on Rose's sister Felicia.
Felicia Karkarov is a student at the Grigori Rasputin School of magic in San Diego - capital of the Holy Russian Empire. As a relative to the tsar, Felicia is at the school not for magic but to be close in case the tsar needs a blood transfusion. In fact, her teachers do not know if she has magic.
On her way to dine with her new in-laws, Felicia is kidnapped and locked in a room. She has no idea who has nabbed her, but she plans to escape.
Harris has created a wonderful alternative history. This is a super fun series. Check out the first one today!
