Finch in a Funnel

Flynn Gilday feels the pull of a final trip in life. No sandy beach for him, he enlists his wife Aggie and their best friends to nine back-to-back itineraries meant to spark revelation. But the unwitting travelers are snared at each stop in a net of anonymous smartphone texts, and, ever more vulnerable, they grow frantic to identify the sender. When a bomb explodes in Venice, the group comes unglued. Flynn Gilday presses ahead on his own, sailing for Tangier before Europe can lock him down. Aboard the ferry, he cries out to the Sahara, a pronouncement, a confession.
