Maya "Lark" Larkin's life shattered when she and her mother were kidnapped by a cartel, a violent consequence of her father's refusal to make deals with them. That day took her innocence and changed everything. At just 12, Lark killed a man in her own bedroom. Her father, Pops, saw potential in her—and began using her to quietly eliminate his enemies without raising suspicion. Before finishing high school, Lark fled River Heights to avoid police scrutiny. She joined the army and quickly became part of an elite unit: Strategic Reconnaissance and Operations Command (SROC). For eight years, Lark and her team, the Daytrippers, carried out covert missions in the shadows. They were good at their jobs. Then came Guam. Captured by a secretive cannibal cult deep in the jungle, Lark was held for a year, along with two teammates—Shoresy and Roke. Only she made it out. What she endured there left scars that went far beyond the surface. After a year of therapy that couldn't piece her back together, Lark is finally ready to return home. But she's not going back to heal—she's going back for revenge. The man who took her father from her, Bilya Bumagin—better known as Billy Boom—has to pay. Armed with the brutal tactics she learned as a teenager and as a government operative, and haunted by Shoresy, the ghost of her trauma, Lark roams the streets of River Heights, ready to force Billy Boom into the light. But as she battles an uncontrollable hunger and the nightmares that plague her, her quest for vengeance might transform her in ways she never expected.
