Sunny Randall's newest client, Blake, seems to have it all: he is an Instagram influencer, with all of the perks that the lifestyle entails - a beautiful girlfriend, wealth, and adoring fans. But one of those fans has turned ugly, and Sunny is brought on board to protect Blake and to uncover who is out to kill him. In doing so, she investigates a glamorous world rife with lies, schemes and ties to Boston's mob. Soon the threats against Blake grow to include personal attacks on Sunny.

Sunny must learn new tricks - and call in old friends - to stop a killer.
