Sadie has seen and done it all as a badass Marine Raider and now top operative at Knot PMCs. She likes her regimented routine, that's free of messy complications. Maxen, a former Delta Force soldier, crashes through all her neatly constructed walls, determined to show her what real passion is. The sexy operative lights her world and bed on fire in the best ways, taking Sadie on the ride of her life. A ride that comes to a screeching halt when a mission to Iran deals a devastating loss to her team. Too late to save a group of US soldiers from a massacre, including one of her own, all Sadie's team can do is handle cleanup and return home. Grieving a teammate and close friend is hard enough, but things take a frightening turn when her partner and best friend, Aaron Hosfeld, is blamed for the attack. Aaron refuses Sadie's help to clear his name and disappears, making matters worse. With the feds convinced they've got their man, a manhunt for the rogue contractor ensues, leaving Sadie and a small group fighting the clock to prove Aaron's innocence. The search for the real culprit sends Sadie and Maxen back to the beginning, but what she finds out about her friend might mean the end for them all. Knot Guilty has a touch of enemies to lovers, unrequited love, unexpected danger, a major plot twist, and plenty of steam.
