This blended a bit of steampunk with a late Renaissance European style world that I really enjoyed. Shadow vampires who possess bodies and a dark religion makes this even more unique.
Isabelle, brilliant but with no magic, agrees to marry a foreign prince in hopes of helping her cousin the king, but she must survive the deadly politics of this new kingdom with the help of her loyal musketeer.
4/5 read for a bit of steampunk & a lot of politics
