This standalone sees two brothers saved from a cult as children, now grown up to become two very different adults. Both are being pursued by a serial killer hell bent on sacrificing them for their divine purpose . . . All angels are not goodness and light. In fact . . . they're some of the most murderous creatures you'll ever come across Former detective Nate Freeman just wants to be left alone as he recovers from the case that ended his career two years ago. As a child, he and his brother Will were saved from a religious fanatic compound in the US and brought to the UK. Now, as an adult, Nate has no idea where Will, or any of the other surviving 'Children of Hamor' are, until they suddenly start turning up dead - minus some skin . . . When his old boss DCI Openshaw asks him to assist in finding the serial killer who is hell bent on collecting the symbols so brutally branded onto the children's backs in the name of Berith - the Fallen Angel - Nate finds himself conflicted. As one of 'the promised' Nate is in mortal danger, and as the case builds momentum Will becomes the prime suspect. It's an intense race against time for Nate to uncover the identity of the 'angelic' serial killer and save his own skin in the process!
