Tiller Galloway Books in Order

The Tiller Galloway novels drop you into the underwater world of commercial diving, salvage boats, and small time smuggling along the Atlantic and Gulf coasts. The series follows Lyle 'Tiller' Galloway, a former Coast Guardsman and Vietnam era SEAL who has done prison time for running drugs and now scrapes out a living as a dive boat captain and trouble magnet.

In Hatteras Blue Tiller is back on North Carolina's Outer Banks, running charters and trying to satisfy the terms of his parole. When a mysterious financier hires him to locate a German U boat sunk off Cape Hatteras, rumored to have gone down with Nazi gold aboard, the job draws in his skeptical parole officer and a mix of modern criminals who see the wreck as their chance to cash out. Treacherous currents, aging equipment, and old war secrets all vie with human greed.

Bahamas Blue finds Tiller and his partner Shad Aydlett barely keeping their small dive and salvage outfit afloat. After their boat and business are destroyed, they agree to work again for Juan 'the Baptist' Nunez, a drug kingpin Tiller swore never to deal with. The assignment, a four hundred foot dive off Green Turtle Cay to recover a lost cargo of cocaine, plunges them into a maze of hostile islanders, corrupt officials, and double crosses.

In Louisiana Blue the pair head for the Gulf of Mexico, where the oil patch offers high pay and extreme risk. Working from crowded saturation diving chambers on deepwater rigs, Tiller uncovers serious damage to a pipeline that could trigger a disastrous spill. Company bosses and his own employer lean hard on him to falsify the report, forcing him to choose between a payoff and the safety of an entire coastline.

The fourth book, Down to a Sunless Sea, shifts to Florida and the world of limestone cave diving. After the death of an old friend in an underwater accident, Tiller travels south with his runaway teenage son, helps run a dive shop, and learns the hazards of exploring flooded caverns. When he discovers that the dead diver was laundering cartel money and that a powerful local figure is quietly diverting water from a massive aquifer, he is pulled into a violent confrontation that tests both his skills and his willingness to risk another stint behind bars.

Across all four adventures, the Tiller Galloway books combine gritty blue collar detail with high stress dives, bar fights, and backroom deals. Tiller is no saint, but his stubborn refusal to look the other way when lives or fragile coasts are at stake gives the series its heart.
