Charlie Madigan, my favorite kick butt, special forces huntress is back in action and trying to save her sister, Bryn, from her deadly addiction to ASH, a drug made from a flower found in the underworld. The drug is making inroads with humans and helps the Otherworlders possess them. Charlie's ex husband's body has been taken over by the Revenant, Rex and is now her go to guy for domestic issues. There are a lot of laughs from his direction. Oh, and her hot siren partner, Hank, has gotten his voice back and Charlie finds herself drawn to him more than ever. Now, she must take all the help she can get, even from the snarky Oracle, Alessandra and go meet with some vicious lady sylphs in search for a cure that will end the humans' addiction to Ash. She should have taken the Oracle's advice and learned to beware of slyphs bearing gifts. These so called gifts cause Charlie a lot of wear and tear, but that which doesn't kill her, makes her stronger.This latest installment is fast paced and humorous filled with romance, action and witty dialogue. Em, Charlie's daughter has matured a bit and understands her mother more and I want to read more about Em. I thought it was wonderful to watch this relationship grow. The more fun lines are delivered by Rex though. If you haven't read the other two books in this series, I don't think you will have a problem jumping right in to this one since there is a nice one page recap done as a report on the first page. Although, you really should read the others first since Charlie's descriptions of the new Underground Atalanta as spectacular. Oh and the HellHound makes another appearance. Can't get better than that!
