But when he learns his son Will died following in his footsteps, he needs answers. What mission took Will up into the alpine heights, and why is Ilya Ivashka on the same trail? Ilya—his close friend, his rival in love. Ilya, who framed Mac for treason and sent him into hiding.
Wiping away the years, Mac returns to the field to find the secrets Will hid and finds himself facing the Herculean task of stopping a terrorist plot that threatens thousands. But in a field of double agents, who can he trust?

Christopher Reich
Most thriller writers imagine the world of spies and secrets. Christopher Reich once lived close to it. Born in Tokyo and raised in Los Angeles, he later found himself deep in the financial underworld of Switzerland—an experience that would shape his debut novel, Numbered Account, and quietly redefine the corporate thriller. From that first breakout success to his latest razor-edged series, Reich has built a body of work that blends precision, global scope, and an unnerving sense of realism.
Mac Dekker
In the Mac Dekker series, nothing is ever just what it seems—not a mission, not a murder, not even the truth. Set in a world where past sins are never buried deep enough, this tense and atmospheric thriller series follows a former CIA operative dragged back into a shadow war he thought he’d left behind. It’s not about saving the world. It’s about surviving the games being played behind the curtain.
Mac Dekker consists of two books and series is set to expand with the upcoming release of one more book. The current recommended reading order for the series is provided below.
