Three men. One mission. Zero margin for mistakes.
When combat medic Tessa Voss is dropped into Black Delta, a covert unit that isn't supposed to exist, the enemy learns her name—and uses it.

A burned village, a hacked signal, and a dossier with her face make one thing clear: someone inside is feeding their coordinates to a ghost broker who wants Black Delta erased. Captain Cole Mercer is ice-steady command, Blitz is the reckless breacher who bleeds laughing, and Devereux is the quiet codebreaker with a blade for a mind. Tessa doesn't flinch for any of them—until orders collide with desire and she's turned into bait.

As ambushes close in and a traitor surfaces, the team goes dark—no uniform, no rules—to hunt an international arms network before it hunts them. Trust is a liability. Chemistry is a weapon. And loving more than one man in a war zone might be the most dangerous op of all.

Steel Hearts is a high-heat military reverse-harem romance packed with battlefield grit, found-family loyalty, and breathless, open-door passion. Expect midnight extractions, morally gray protectors, and a heroine who saves lives, takes the shot, and claims every piece of her heart.
