Nick Lassiter-Skyler International Espionage Books in Order

The Nick Lassiter-Skyler International Espionage series begins with an everyday problem that quickly becomes anything but ordinary. Nick Lassiter is a struggling writer from Colorado who discovers that his unpublished thriller appears to have been stolen, turned into a successful novel, and adapted into a major movie. He wants an apology and the truth. Instead, he gets pulled into a much bigger mess.

In The Devil's Brigade, Nick heads to New York with close friends to confront the author and literary agent he believes wronged him. The trip turns into a collision with law enforcement, Russian organized crime, and a CIA counterintelligence operation. Nick is not introduced as a polished spy. He is angry, determined, and badly out of his depth, which gives the first book an underdog energy alongside its chases and conspiracies.

Then the scope expands.

The Coalition shifts the focus to Skyler, a skilled assassin caught up in a political killing with national consequences. FBI agent Kenneth Patton and reporter Jennifer Odden follow the trail toward a secretive organization seeking influence at the highest levels of government. The book moves through Denver and Colorado Springs as the investigation becomes a race to identify the people behind the violence.

In The Fourth Pularchek, Nick and Skyler's stories draw closer together. Nick learns that Polish billionaire and intelligence figure Stanislaw Pularchek may be his biological father, sending him toward Warsaw and a tangle of family history, international operations, and unresolved World War II crimes. Skyler has her own dangerous role in Pularchek's world, while enemies connected to an old Nazi legacy pursue their own agenda.

The trilogy mixes contemporary action with questions about identity, loyalty, and how the past can keep shaping present-day conflicts. Colorado, New York, Washington, D.C., and European cities all matter to the action, but the books keep returning to people forced to decide what they will do when institutions fail them.

Expect political intrigue, assassins, intelligence agencies, and broad conspiracies, with a little humor in the opening book's fish-out-of-water setup. Start with The Devil's Brigade, formerly published as The Slush Pile Brigade, for Nick's origin story. Read The Coalition next, then The Fourth Pularchek to see the series bring its central characters and international threads together.
