Wendy Cross‘s debut YA SF crime novel mixes AND THEN THERE WERE NONE by Agatha Christie with SURVIVOR but while the pacing is fast, it cannot make up for very thin characterisation (including of the 3 POV characters), equally thin world building (with Cross heavily dependent on mentioning an aspect of this universe when she needs to explain a twist) and some heavily foreshadowed twists so that as a result the novel just didn‘t work for me.
