CIPHER: Lethal Algorithm (US Marshals: Task Force 9 Book 2)

A legendary hacker on the run. A dominant US Marshal sent to capture her. One island safe house.

You've spent three years running from the monsters who burned your life to the ground — and now the only safe place left to hide is in the arms of the man sent to capture you.

Ivy is a ghost. The legendary hacker known as "the dragon," she survives on cold logic, burner laptops, and one steel-clad rule: never leave a footprint. She burns the Consortium's financial networks to make them pay for the friend they stole from her, and she never stays anywhere long enough to let the world touch her. Until a high-stakes zero-day in Macau goes wrong, and she's cornered in a dark parking garage.

Enter Julian Rhodes. US Marshal. Task Force 9 — the off-books federal unit that handles the targets who don't exist. He's spent eleven weeks tracking a shadow, and he isn't about to let her slip. Cocky, controlled, and hyper-confident, Julian lives to own the room. But when he finally captures his target, he doesn't find a cold corporate threat. He finds a sharp, defensive genius whose isolation trips every protective instinct he's spent his career locking down.

Forced into proximity in a remote island safe house, they run a joint extraction against a degrading seventy-two-hour window. His steady, load-bearing calm meets her razor-fast digital shields, and the friction sparks a heat neither can control. Under his roof, Julian gives her something she's never let herself have — the grounding safety she's been starved for since the day she ran.

Then a brutal ambush compromises their extraction, and Ivy makes the ultimate play to keep him alive: she cuts him out, secures the drive, and vanishes into the cold Shinjuku rain.

Julian doesn't take abandonment lightly. He survived the crossfire, and he's crossed an ocean to bring his ghost home — a digital trap built to catch her one-of-a-kind signature, waiting for the moment she slips. Because once you surrender to a protector, he never lets you run again.
