The Tsarina's Daughter by Carrolly Erickson
Erickson has proven herself a master of rewriting the history of famous women (Marie Antoinette, Josephine Bonaparte, Catherine Parr) in a fictional setting, and this title is no exception.
In this title, set in Russia shortly before the revolution and deposition of Czar Nicholas, we are let into the life (and loves) of Tatiana Romanov, given a front row seat into her mother's madness, the dealings of Rasputin, and the slow degradation of worker rights on the eve of revolution.
Though we know that Tatiana was executed along with the rest of her family, Erickson imagines a very different end - Tatiana lives, and flees with her lover, making a new life in the new world. A much happier ending that the grim true one.
This is a well-researched, interesting read in a subject I've long been fascinated by. Well done!
