Last Girl Ghosted

Advice columnist Wren Greenwood, the protagonist of this enthralling psychological thriller from Thriller Award finalist Unger (Confessions on the 7:45), meets Adam Harper after she joins the online dating app Torch. Wren and Adam begin an emotional affair that she believes will last, but three months later Adam vanishes, ghosting Wren by deleting all his contact information, including his Torch profile, and disconnecting his cell phone. Wren is further devastated when a private investigator shows up at her Brooklyn townhouse claiming that Adam may be responsible for the disappearance of three women, who, along with all their money, have never been located. The search for Adam forces Wren to confront her turbulent childhood, which included a violent father who insisted his family live off the grid. Readers will root for the appealing, intelligent characters, even when they’re not acting in their own best interest. Believable plot twists related to questions of identity and the value of friends who become family further elevate the story. Unger is on a roll. Agent: Amy Berkower, Writers House. (Oct.)
