No one does time travel/portal travel like Shay West. We meet Tai and Keena who are young and definitely not from our world. They are harvesters. What are harvester? They harvest the organs needed on their world from humans on earth. Being a harvester is not only considered an honor, but comes with perks for the whole family. Their religious beliefs don't allow them to take organs from their own deceased, and that is why they come to earth. One assignment is just too much for them so they decided there must be a way to stop all of the killings.
Eli and Ava are the two detectives stuck with this mystery. These detectives have very realistic flaws. Eli drinks too much, having caught his wife with the neighbor and then divorcing her. Ava is a good balance to Eli.
Master Kelhar is the one sending out the harvesters. But, is he just pure evil? Is there a way to stop him? Find out what happens when Eli and Ave join forces with Tai and Keena. As always Shay West does an excellent job of story telling. I would recommend all of her books. She did an excellent job of keeping the pace so that the reader sits on the edge of their seat waiting for the next event.
