BI Special Agent Matthew Roarke is closing in on a bust of a major criminal organization in San Francisco when he witnesses an undercover member of his team killed right in front of him on a busy street, an accident Roarke can’t believe is coincidental. His suspicions put him on the trail of a mysterious young woman who appears to have been present at each scene of a years-long string of “accidents” and murders, and who may well be that most rare of killers: a female serial. Roarke’s hunt for her takes him across three states…while in a small coastal town, a young father and his five-year old son, both wounded from a recent divorce, encounter a lost and compelling young woman on the beach and strike up an unlikely friendship without realizing how deadly she may be. $3.99 on Kindle.
