The Specialist Books in Order

Jack Sullivan is hired to kill an exiled African dictator living in France, and the job quickly turns savage. This is the series opener, all anger, weapons, and ruthless momentum.

Mediterranean intrigue, hired killers, and a revenge job with international reach push Sullivan into another hard sprint. The book keeps the series' mix of travel and carnage.

Sullivan brings his methods to New York, where revenge means cutting through urban power, organized violence, and crowded danger. The city gives the series a tighter, meaner arena.

A job turns personal as Sullivan is pushed toward enemies tied to his own past. That shift gives the third book a more intimate and nastier kind of fury.

A threat large enough to justify the title drops Sullivan into another all-or-nothing mission. The pace is fast, the body count rises, and subtlety does not get much of a say.

Sullivan faces opponents who are not just well armed but disturbingly unstable. The result is one of the series' more brutal mixes of military hardware and human wreckage.

The action comes home as Sullivan faces enemies on American ground. It is another revenge mission, but one that feels closer, dirtier, and more personal.

Sullivan is pulled into Middle Eastern violence where terror, politics, and revenge overlap. The series' usual one-man-war formula gets a harder international edge here.

Sullivan ends up defending a threatened stronghold against wave after wave of armed attackers. The setup is simple, brutal, and perfectly matched to the series' hard-pulp energy.

Jack Sullivan takes on another revenge job and finds that the target is tangled up with his own darker impulses. The mission is global, violent, and built for one-man retaliation.

A remote and dangerous setting gives Sullivan one more stage for payback. He heads into rough country where ambushes, hired killers, and old debts are waiting higher up the slope.
