Thin Air

by Lisa Gray

Published 1 June 2019

A Washington Post, Wall Street Journal, and Amazon Charts bestseller.

“Lisa Gray explodes onto the literary stage with this taut, edge-of-the-seat thriller, and her headstrong protagonist, Jessica Shaw, reminiscent of Lee Child’s Jack Reacher, delivers a serious punch.” —Robert Dugoni, New York Times bestselling author

Private investigator Jessica Shaw is used to getting anonymous tips. But after receiving a photo of a three-year-old kidnapped from Los Angeles twenty-five years ago, Jessica is stunned to recognize the little girl as herself.

Eager for answers, Jessica heads to LA’s dark underbelly. When she learns that her biological mother was killed the night she was abducted, Jessica’s determined to solve a case the police have forgotten. Meanwhile, veteran LAPD detective Jason Pryce is in the midst of a gruesome investigation into a murdered college student moonlighting as a prostitute. A chance encounter leads to them crossing paths, but Jessica soon realizes that Pryce is hiding something about her father’s checkered history and her mother’s death.

To solve her mother’s murder and her own disappearance, Jessica must dig into the past and find the secrets buried there. But the air gets thinner as she crawls closer to the truth, and it’s getting harder and harder to breathe.

An isolated highway in the middle of the desert—the perfect place to hide a secret.

LA-based artist Laurie Simmonds disappeared two months ago, her campervan abandoned on the isolated Twentynine Palms Highway, miles from anything—or anyone.

But no sooner do they follow this up than Laurie’s parents get spooked and drop the case. Jessica is blindsided but determined not to give up: three women are missing, and many more may be at risk. She can’t turn her back on them. But the more she pulls at the threads of the truth, the closer she comes to danger. Can she find out who’s behind these crimes before they come for her?
