If I Should Die by Amy Plum

I haven't read the first two books but I know that I would enjoy them.  Book 3 dives right in and catches the reader up with the unusual characters.  It's a love story of the supernatural kind between a human teen girl and a guy who's be been dead but is alive and immortal (no not a vampire or zombie).
It's a page turner with lots of action and even a good old fashion sword fight.  We get to travel in Paris and also New York City.   A good read.
