"A man is found wandering the desert outside Las Vegas. The cards in his wallet identify him as Samson Greene, a Columbia University English professor last seen leaving campus eight days ago. Thirty-six years old, with a wife, Anna, and a dog, Frank. But Samson doesn't even recognize his own name, and by the time Anna has make her way across the country to pick him up, doctors have discovered a cherry-sized tumor in his brain; its removal eradicates the last twenty-four years of Samson's memories." "Samson and Anna return to New York together, where Samson struggles to connect with the woman he knows he is supposed to love, with his career, with his home, with his "life"." "Into these daily lives fraught with a peculiarly intimate tension comes a charismatic scientist who invites Samson to take part in a groundbreaking medical experiment in the Nevada desert. It doesn't take much to lure Samson away from his profound loneliness in the city, where he is stuck between missing the past life that surrounds him and yearning to enjoy the fresh start he's been given. But Anna is never far from his thoughts as he embarks on the journey that promises adventure and revelation but may mean the end of the old Samson Greene."--Jacket.
