I had this as both a review copy and an audiobook from Netgalley. I usually listen to audiobooks on my phone. I'm not sure what the difference is between a Netgalley audio and an Audible audio, but while listening my phone got so hot that I had to switch it off. So I listened to the first half and read the second half. The audio was well read by Sophie Aldred, but I think I got more out of the text.
Two girls (lovers) went tramping over Dartmoor to hunt cryptoids, and only one came home. Despite investigations and search parties, Lee survived but Mal was never seen again… until four years later. Julian Sabreur, MI5 agent, is investigating an attack on top scientist Kay Amal Kahn – an attack dramatically and violently thwarted by strange-looking people who might be agents of an unknown power. And there in the grainy CCTV footage is an image of a girl, missing, presumed dead on Bodmin Moor.
Cracks between worlds are opening up and might be about to end all life in the universe. This book goes from a small-scale mystery to a major crisis involving parallel worlds. Sciency but still portraying interesting characters this is a book that delivers on many levels.
