Interesting. From the list of her previous novels I see this isn't her first foray into historical non-fiction (Ben Franklin, the Lincoln's, Eleanor Roosevelt, Amelia Earhart, etc). Are they all designed for children?
It probably won't make it onto my personal bookshelf, but I think it's great, as your mentioned, that someone is writing these types of introductory stories for the roughly 12-18 year old crowd. So much out there is either childish fantasy-fiction (Anastasia), dry historical (Fate of the Romanovs), or for the longtime Romanov devotee (insert title here _____ ). There's someone in particular I know (advanced 14-year old daughter of a friend studying the Russian language) that I'll recommend it to!
