The writer Benjamin Moser signed an agreement this week to write the authorized biography of Susan Sontag, the legendary novelist, essayist and critic who died in 2004 at 71.
Ms. Sontagâs son, the writer David Rieff, and the literary agent Andrew Wylie approached Mr. Moser about the project. Mr. Moserâs biography of the Brazilian writer Clarice Lispector, âWhy This World,â was a finalist for a National Book Critics Circle award in 2009.
Mr. Moser, who grew up in Texas and now lives in the Netherlands, said in an inteview via e-mail that he expected the book to take at least three to four years to complete.
âItâs only since Iâve started reading her from A to Z that I realize how much she wrote and did,â Mr. Moser said. âHow everywhere she was. Itâs hard to think of a writerâs life that ranged as widely.â
