This was fantastic, especially for a debut. I recommend it for younger readers teens and the early twenties, older readers may find it a very quick and easy read. Beautiful and great world building. Includes Maps and a glossary for those of us who are unfamiliar with The underworld of Scion London in the year 2059 or the hidden prison for clairvoyants, run by creatures of death incarnate known as the Rephaim, Sheol I.
