Former Army Ranger Serena “Rena” Cross has spent her life fighting battles most people could never imagine. When she’s recruited by the legendary Expendables, she becomes the youngest—and only female—member of the world’s most dangerous team of mercenaries. To Barney Ross, she’s family. To the team, she’s the little sister they never asked for but would die protecting. To Lee Christmas… She’s the one person he can never seem to let go. Their relationship is a constant cycle of passion, heartbreak, and second chances, unfolding between impossible missions and impossible choices. Every time they swear it’s over, another mission throws them back together. Beginning with the events of The Expendables, Serena fights alongside the team through international firefights, impossible rescues, and life-or-death missions that span more than a decade. As old enemies return and new ones emerge, she’ll discover that loyalty is earned, family is chosen, and love can be just as dangerous as the battlefield. Because when you’re an Expendable…The mission always comes first. But some people are worth risking everything for.
