One for all

In 1655 sixteen-year-old Tania is the daughter of a retired musketeer, but she is afflicted with extreme vertigo and subject to frequent falls; when her father is murdered she finds that he has arranged for her to attend Madame de Treville's newly formed Acad?mie des Mari?es in Paris, which, it turns out, is less a school for would-be wives, than a fencing academy for girls--and so Tania begins her training to be a new kind of musketeer, and to get revenge for her father.
