Author J.J. Green brings us Jas Harrington's next adventure. Jas and her friends are forced out of their hiding spot in the main building of the underworld by the former leaders followers. That leader who went missing while they where trying to catch a Shadow. As Jas and her group make it to the former underworld leader's safe house they find her there on the stairs and calling out a number that in turn is for a doctor and her former friend. The events heat up from there as they are once again forced out of the safe house and the minster that they had captured was killed. This is a great book and an easy read and I highly recommend this entire series. I only have four books to go before I finish this series and I am looking forward to reading the next book.
