Nikki Fuller has always known she was different. At twenty years old, she's the oldest Fuller daughter, feisty, outgoing, and never one to back down from a fight. But Nikki also sees things other people don't-shadows that move wrong, danger before it strikes, and monsters hiding behind human faces. Her family thinks she's just sensitive. Nikki knows better. When a family trip turns into a nightmare, Nikki's world collides with the Gecko brothers-Seth, the sharp-tongued bank robber with a dangerous smile, and Richie, the violent wildcard with darkness in his eyes. They take her family hostage, dragging them toward Mexico with the FBI and Texas Rangers closing in behind them. But Nikki doesn't fear the brothers the way she should. And the Geckos don't know what to do with a girl who talks back, sees through their masks, and somehow gets under their skin. By the time they reach the bar where they're supposed to meet safety, everything changes. The place is crawling with something ancient, hungry, and deadly. Vampires are real, blood will spill, and survival becomes the only rule that matters. But in the middle of the chaos, Seth and Richie find themselves becoming dangerously protective of Nikki. And Nikki may be the one thing the monsters should have feared all along.

Masey Fuller never wanted to be on this trip. At twenty-one, she is the oldest Fuller daughter, the outgoing, fiery one who would rather be anywhere else than trapped on the road with her family. But after being guilt-tripped into coming along, Masey tries to make the best of it. That changes the second they pull up to a rundown hotel and cross paths with the dangerous Gecko brothers. Seth and Richie are supposed to be the enemy. They abduct her family, drag them into a nightmare, and turn Masey's world upside down. But instead of fearing them the way she should, Masey sees something beneath the threats and blood. Seth is sharp, protective, and always watching. Richie is darker, haunted by something he can't fully control. When the group is forced into a deadly fight against vampires, Masey becomes the one person who can reach Richie when the vampire queen tries to sink her claws into his mind. Now Masey has to protect her family, survive the night, and figure out why the two most dangerous men she's ever met suddenly act like she belongs to them. Fiesty, fearless, and impossible to ignore, Masey Fuller may have been dragged into hell... ...but the Gecko brothers are about to find out she bites back.
