How far would a mother go to save her daughter?

Simone Seaborn leaves her home in London for southwest Texas to meet her teenage daughter, Lucy, who’s spent the summer there before starting college. The two have planned a camping trip as a reunion after the longest period they’ve ever spent apart. But almost immediately, the trip seems cursed: Simone’s suitcase is lost—maybe even “on the moon,” according to an airport attendant. She and Lucy are reunited at their Airbnb stopover, only for Simone to wake in the morning and find Lucy missing. Left behind: a phone that begins to ring, “Caller Unknown.” Lucy has been kidnapped. Simone immediately snaps into action, following all the kidnapper’s instructions, including not to notify the police, a decision that her husband, Damien, strongly opposes. She travels to the meeting place only to be sent across the border to Mexico, where she must pick up a package and bring it back to Texas. Simone and Lucy are eventually reunited, but by then things have gone very wrong: Simone shoots the messenger who brings Lucy to the meetup, and then Lucy accidentally shoots an off-duty cop who’s coming to investigate the noise. On the run in the rural Texas desert, mother and daughter strike out to save each other and to clear their names. The plot is convoluted, and even a little absurd, but it keeps you guessing. What truly shines through in McAllister’s fluid prose, though, is the love. This is a novel about motherhood, and mothers and daughters, and the transition from childhood to adulthood. It’s about sacrifice and loss, but also joy, and the tenuous beauty of each moment of life. It’s about saving the day in even the direst of circumstances, and how love between a parent and child is never a loan, but exists forever—past, present, and future—even as time inevitably slips by.

Come for the action, leave deeply moved by the fiercely beautiful meditations on maternal love.
