The Blackmail Code, #2
THE BLACKMAIL CODE
Book Two of The Port Allegiance Chronicles
Abbie Spencer is finally building a life somewhere close to safe—a road trip, a slow-burn maybe-something with Dylan De Young, the wealthy heir who helped pull her out of hell, and the fragile comfort of knowing her friend Gia is recovering well after escaping Terra Isle.
For the first time in forever, Abbie can breathe.
Then Gia and her girlfriend, Skyla, are kidnapped before the four of them can enjoy their long-awaited reunion in San Francisco.
The architect of their nightmare: Hilda De Young, Dylan’s own mother, who’s locked behind bars at Alcatraz. She’s found a way to continue her evil ways, and demands one thing in exchange for Gia’s and Skyla’s freedom: a black book hidden inside her beloved Redwood Manor. Her only condition: Abbie must deliver it alone.
Events quickly spiral into a high-stakes hunt through secret data drives and hidden labs, where doctors conduct unspeakable experiments. Now torn between love and rage, survival and justice, Abbie and Gia must both decide what they’re willing to risk, and who they’re willing to become to stop the people who see them as disposable.
THE BLACKMAIL CODE is a dark, propulsive mystery/thriller about what happens when survivors of horror refuse to be quiet, compliant, or forgive those who tried to destroy them.
