Kristin Hello. I follow Kalayna on Facebook and she recently apologized for the hiatus. She announced Grave Visions will be out in February 2016.
Marsha It's been so long since the last book, I forgot what the series is about (Lol). I'm not sure I want to read this and then have to wait another two years for book five!
Lib (Enthusiastic reader, occasional reviewer) I noticed that release date on Amazon too - Dec 31, 2099 - maybe they're just being optimistic.. lol. Wondering where the August update came from... I cant' find a date anywhere..??
