Very enjoyable read which left me wanting more. The storyline kept moving and never stopped. The questions about Jane are a powerful mystery which the reader wants to solve.
In some ways it is simplistic with a single storyline and two primary characters. There wasn't very much worldbuilding or background, but just enough.
If you want a complex epic multi-thread story, and very detailed scene setting, look elsewhere. But for a fun read, this will do nicely
