Sam Deker Books in Order

The Sam Deker novels pull Thomas Greanias's fascination with time, faith and warfare into a harsher register. Sam is an Israeli counterterrorism agent and demolitions specialist who has already lost the woman he loved by the time readers meet him. Where Conrad Yeats hides his wounds behind charm, Deker is all sharp edges and buried guilt. His stories swing between modern threats and ancient battlefields, asking what it means to fight for survival when history itself seems to be shifting under your feet.

The Promised War opens in present day Jerusalem, where Deker stops an attack on the Temple Mount that is meant to ignite a regional holy war. The victory is brief. He is abducted, tortured for Israel's most closely guarded failsafe, and left hovering between life and death. When he wakes, he is no longer in a cell but in the camp of Joshua's Israelite army on the eve of the siege of Jericho. The book never fully answers whether he has traveled through time or is trapped inside a weaponized hallucination.

Either way, Deker is ordered to spy on the walled city and report back on its defenses. He crosses into Jericho with a fellow soldier and meets Rahab, the enemy whose choices will matter as much as his own. The familiar outlines of the biblical story are there, but the book leans into the mud, fear and moral ambiguity of a small force trying to secure a homeland. Deker has to decide what kind of violence he can live with, and what faith looks like when you are the invader.

In The 34th Degree the battleground shifts from Bronze Age Canaan to Nazi occupied Greece. Back in the present, Deker has been dishonorably discharged and is trying to disappear in Los Angeles, haunted by flashbacks and the strange side effects of the torture he endured. The Pentagon recruits him into a classified neurosimulation program that uses preserved brain tissue to drop his consciousness into the past. His target is SS general Ludwig von Berg and an ancient manuscript whose formulas describe a thermodynamic Greek fire that could end the world.

Deker experiences 1943 through the eyes of Greek shipping heir Chris Andros, navigating resistance cells, occupied Athens and the general's circle of power. The lines between host body and intruder, and between past and present, keep blurring. The same shadowy Alignment that stalks other Greanias books is racing to seize the manuscript for its own purposes, and Deker has to work out whether changing events inside the simulation can actually rewrite history or only reveal the truth about his own century.

The Sam Deker books are intense, sometimes brutal, yet they stay grounded in character, always circling back to one soldier's struggle with loyalty, trauma and what it means to be responsible for a nation.
