Former black ops agent Brady Hawk is enjoying his new life with his growing family on a ranch in Montana. Then the former head of the CIA pays Hawk a visit to discuss a dangerous assignment: extracting one of Hawk’s Navy SEAL friends stuck in Siberian Russia. Unwilling to leave his pal behind enemy lines, Hawk agrees to accept the mission. But when he arrives in Russia, he finds that everything isn’t as it seems, while uncovering a secret that could have far-reaching implications on the country’s national security.

Meet Brady Hawk. Former Navy SEAL. Former Peace Corps worker. Current blacks ops assassin. To those with the highest security clearance, it's a line item known only as Project X. But to the half-dozen agents and personnel working for it, it's known as Firestorm, a black ops group so dark that the US president doesn't even know about them yet. And no agent is as skilled as Brady Hawk.

Jon Reznick is a “ghost”: a black-ops specialist who takes his orders from shadowy handlers, and his salary from the US government. Still mourning the loss of his beloved wife on 9/11, he’s dispatched to carry out a high-level hit. Reznick knows only that it must look like suicide. It’s textbook. But the target is not the man Reznick expected. The whole setup is wrong.

Dante Jacoby is a slave to the trappings of the modern world. Twenty-six years old and hopelessly addicted to booze, cigarettes, and procrastination, he’s squandered every ounce of his potential. His corporate raider father, Dorian, reaches the end of his tether and cuts Dante off as heir to the Jacoby family fortune. His mother, Fiona, is smarter than her husband: she hasn’t spoken to Dante in months. But Dante’s no victim. He knows he brought this on himself.

US Marshal Arliss Cutter is a born tracker. Raised in the swamplands of Florida, he honed his skills in the military, fought in the Middle East, and worked three field positions for Marshal Services. When it comes to tracking someone down - or taking someone out - Cutter's the best. But his newest assignment is taking him out of his comfort zone to southeast Alaska. Cold, dark, uninhabited forests that are often shrouded in fog. And it's the kind of case that makes his blood run cold.
