Chrissie is a happily married graphic designer with a young daughter. She lives a pretty comfortable and unremarkable middle-class life, but when she receives a visit from a creepy, mysterious stranger, things turn completely out of the ordinary.
Substitute by Susi Holliday has all the elements of a gripping domestic noir, complete with sharp twists and turns, dark secrets, and seismic blasts from the past.
But there is also a techno- thriller aspect to the book that nudges Substitute into Black Mirror territory and gives it an extra layer of intrigue.
Substitute by Susi Holliday is a cracking read and is very, highly recommended.
