Sometimes I need books like this – addictive, straight forward and a bit dark. For times when escapism comes a little less easily because I am travelling or my mind is buzzing or the world is weighing heavily. I picked this up because all of those things were going on. It is got me through some restless nights, tough days and long train journeys. It is a ridiculous story about a former special-ops soldier, Maya Stern, who has just buried her husband and then sees him on the “nanny cam”. Cue sinister wealthy in laws, army flashbacks, improbable connections to the death of Maya’s sister, an Edward Snowden type character and suspiciously loyal best friends. Harlan Coben is a master of this stuff and I loved and lived every moment of it. Job done.
