River of No Return — David Riley Bertsch

High season is coming to an end when Jake Trent, “a fishing guide with a shadowy past, is lured into an explosive situation” (Kirkus Reviews). As the ex-lawyer ponders rekindling his romance with park ranger Noelle Kimpton, a surprise call from a long-lost love throws his life into disarray. It's been years since Jake last saw Divya Navaysam at their law school graduation. Now a DC lobbyist, Divya wants Jake to come to Washington for a consulting job. He books a ticket, wondering what she is keeping from him.

Meanwhile, back in Jackson, Jake's best friend and occasional employee, J.P., is nursing his own romantic wounds. J.P. has fallen head over heels for Esma, but after a perfect summer together, she has returned to her native Mexico -- and before long she drops off the grid completely. Has something terrible happened to her? When local police offer little help, a distraught J.P. turns to Jake. Jake must find Esma and manage a heated relationship with his ex-flame in order to solve the crisis.
