Brannon Hardegree, a Veritas operative and former Army Ranger, finds his undercover assignment increasingly dangerous. After being forced to participate in an armed robbery--or have his deep cover blown--Brannon is ordered to take a portion of the loot on a swamp tour, one headed deep into the Georgia wilderness. There he hopes to "join up" with Quinton Ellers, the leader of a violent anti-government militia who has vowed to "water the tree of liberty" to kick-start the coming revolution. Brannon's job is to stop Ellers before he has a chance to use his cache of military-grade explosives. For former Marine Sergeant Caitlyn Landry, just back from Afghanistan, the swamp offers a brief respite from her debilitating flashbacks. When Cait's former commander, now the owner of the tour operation, is injured in a mysterious car crash, she reluctantly agrees to lead the tour. Still, she knows that her time is running out, that soon she'll stop fighting the darkness and end the pain. What begins as a peaceful canoe ride into the swamp quickly becomes a nightmare. When the loot is stolen and the other campers taken hostage, Brannon and Cait are the only ones who can stop Ellers's murderous plans. To defeat their ruthless enemy, they will need every bit of their courage. To fail is unthinkable, even if it means destroying their one chance for a future together.
