Delta Retribution by Cristin Harber book cover

DELTA: RETRIBUTION

Trace & Marlena
Mistaken Identity • Revenge • Navy SEAL • Tortured Hero

A man is nothing without his team.

Trace Reeves was one bad day from a dishonorable discharge. One of the best the Navy SEALs had to offer, he became a vengeful, angry mess after his twin brother was killed in action. Now he’s focused on a deadly obsession and unable to cope with the pain and guilt.

Titan Group’s Delta team wants ghosts—the best of the best, operators who can live off the grid and surface when commanded. Trace is the perfect recruit: damaged, heroic, and with nothing left to lose.

But when the woman from his unforgettable one-night stand becomes his high-value target during a black-ops mission, the lines blur between rescuing her and saving himself.

Delta: Retribution launches the Delta series and can be enjoyed without reading the Titan books first.

Luke Brenner takes an off-the-books job on a joint task force with one goal: shut down sex traffickers and get closer than ever to avenging the first love who was taken from him.

Madeleine Mercier is the daughter of an infamous cartel family. She knows the money, the power, and the evil behind her father’s empire—and she may be the only person capable of bringing it down.

She sees no escape until she clashes with a mercenary who gives her something she never expected: hope.

The hunter and the woman he should see as prey are forced together. The question is whether they’ll run from one another, destroy each other—or find something worth fighting for.

Then she disappears.

Delta discovers that Victoria was never a helpless victim. She’s a one-woman vigilante force who has taken on gun runners, criminals, and a dangerous motorcycle club. Now Ryder is coming after her—with backup—whether she wants it or not.
