When the world is on fire, the only way to survive is by Acting on Instinct .

Ty Newcomb, Tier One Delta Force operator, and his tactical K9, Rory, are trained to move fast, strike hard, and complete the mission. Ty has built his life on control—and on secrets. Years ago, under CIA orders, he used psychological manipulation to win Kira's heart. He followed the script, but the love that grew between them was real. Now he's done with the world of shadows—and determined to show Kira she can trust what they feel is real.

Kira knows something is wrong. They tell her it's PTSD—a lingering shadow from the terrorist attacks that nearly took her life. But her instincts say otherwise.

A cryptic warning arrives from halfway across the globe, pulling Kira into a fast-moving conspiracy tied to the international power elite and a man willing to destroy anything in his path—including his own family. Kira realizes she isn't a survivor because the dangers aren't in the past; she's still a target.

When Kira goes on the run to save her life, Ty and Rory move into action.

From Spain to Tanzania, Ty and Rory will cross continents to find Kira and destroy the threats that jeopardize their future together.

Escape into a high-stakes global chase where love and betrayal collide, featuring a battle-hardened protector, a brilliant heroine, and the unbreakable bond of a tactical K9 team. Acting On Instinct is a slow-burn, steamy but closed-door, action-adventure romance packed with adrenaline, heart, and the power of found family.
