Twilight Tactics

He came to protect a witness. She came to teach survival skills. Now they're targets with an enemy who won't let either of them walk away. FBI agent Sully Sullivan arrives at Broken Chains Ranch with Ollie Callahan--a foster teen and sole witness to a mob hit. The ranch, started by Sully's cousin to provide a trauma recovery facility for veterans, should be a place he can keep Ollie safe until the trial. But what was meant as a peaceful haven becomes a battleground when armed attackers surround the property. Survival expert Elena Thompson teaches wilderness skills at the ranch and coaches Ollie in self-defense. As the series of attacks on the ranch escalates into a full siege, the question becomes who are the attackers after: Ollie, the young witness? Or Elena, with her mysterious past? With communications down and help out of reach, Sully and Elena fight to keep everyone alive as secrets and danger close in.
