Jen I think at the end there are enough open ends as to leave it open to more. It's good and bad. Only bad because now I want more!!

CapesandCovers As of right now I believe it is, but there is a short story set before this book, called Trigger.

Maria I'm not sure but I think it's a series (https://www.goodreads.com/series/1508...)
