Into the Deep (Delta Shield Security)

Assigned to protect his best friend’s sister, a battle-hardened operative must break every rule in the book to keep her—and his heart—safe in this pulse-racing romantic suspense novel by Wall Street Journal bestselling author Brittney Sahin.

Audrey Langston is done with love. After heartbreak, betrayal, and secrets that shattered her life, all she wants is peace—and to raise her son in safety. But when a violent home invasion rips that fragile calm apart, she’s thrust into a web of shadowy enemies, where someone is watching her. Hunting her. And the threat may be tied to a past she thought she’d escaped.

Alejandro Rodriguez doesn’t trust easily, not after the woman he once loved nearly killed him. Which is why protecting Audrey should be just another mission—the problem is, it’s personal. She’s not only his team leader’s newly discovered sister, but she’s also the woman he’s spent the last two months trying to resist.

As danger closes in and buried lies come to light, the lines they’ve drawn begin to blur. Passion ignites, trust is tested, and every step takes them deeper into a deadly game.

In a world where nothing is as it seems, their intense connection may be the only truth left…if it doesn’t destroy them first.
