Title: Foreign Body - Didier van Cauwelaert - book
Summary :
Can one change one's life for love, become someone new under another identity, without sacrificing one's usual existence? This is what Frédéric will dare. At eighteen, he had published a novel under the name Richard Glen that went unnoticed, then he had given up writing; he had conquered Paris in another way... But one day, a young student from Bruges sent a letter to this forgotten pseudonym, to this part of himself that had been dormant for more than twenty years.
From unknown temptations to the joys of imposture, he will invent another past, another present in Karine's eyes, making Richard Glen more and more real, more and more alive... But how long can two personalities share a body?
With his humor and relentless tenderness, the novelist of Un aller simple , winner of the 1994 Prix Goncourt, draws us into a poignant story that explores the secret dream of many of us.
