RED RIVER ROAD

Two damaged women band together to find the sister of one of them, who went missing during a solo tour of Australia.

Phoebe Sweeney is, or was, a massage therapist and yoga instructor who rejoiced in the prospect of circumnavigating Australia by herself. Beginning with the long drive north from Perth, she left pictures and posts on social media as she went. Her silence since Valentine’s Day devastates her sister, Katy, a Sydney schoolteacher who resolves to retrace Phoebe’s steps in her own HiAce van in search of her. Her quest is fraught from the beginning, since Vivi Green, another solo traveler, has already vanished from the region. And things rapidly get creepy when Katy encounters two different strangers, a man and a woman, who want to join her. Katy brushes off the man, who claims to know a good deal about her and Phoebe, but she can’t abandon Lily, the injured woman who climbs out of another van, approaches her, and begs for help. So she takes her in, shares stories with her, and invites her along. She’d certainly act differently if she knew that Lily was really Beth Randall, a thief on the run from Lucas Cleary, her abusive partner in crime. But then Katy has secrets of her own that Beth can’t imagine. Although the geographic sweep of the two women’s journey is vast, the list of characters is tiny. So Downes builds suspense by deftly unpacking one layer of deception after another, never forgetting that her two travelers face danger not only from each other but from every man who catches sight of them.

The Australian Tourist Board will never endorse this road-trip nightmare. But readers are likely to recommend it highly.
