For Arthur Less, life is going surprisingly well: he is a moderately accomplished novelist in a steady relationship with his partner, Freddy Pelu. But nothing lasts: the death of an old lover and a sudden financial crisis has Less running away from his problems yet again as he accepts a series of literary gigs that send him on a zigzagging adventure across the US.

Receiving an invitation to his ex-boyfriend's wedding, Arthur, a failed novelist on the eve of his fiftieth birthday, embarks on an international journey that finds him falling in love, risking his life, reinventing himself, and making connections with the past.
