The Exphoria Code, by Antony Johnston (Lightning Books, 2017)

A troubled MI6 hacker finds evidence of a spy inside a top-secret military coding project. Zippy high-tech thriller with lots to recommend it – not least its protagonist, who has series potential – even if the third act wobbles a bit in comparison to earlier aspects of the book. Well worth the read though.

My own books are here, if that’s your thing. Newest is noir thriller East of England.
