Well this one was an interesting audiobook, we get a reverse harem with 4 sexy guys with special abilities. Tyler, Ethan, Alec and Josh who are Variants and to use their ability they need a Vital, so yes Eve is the vital they all need. So there is more into the story than the regular reverse harem you might think. I enjoyed it, the narrators Janine Granada and Jarred Kjack did a great job, this is book one and there are 3 books.
