“Each book has an individual, singular voice…some are very interior, some are very extravagant,” says Xiaolu Guo, one of the judges for the 2019 Booker Prize, about the thirteen titles nominated for the longlist of the prize. The “Booker Dozen” includes The Testaments by Margaret Atwood, My Sister, the Serial Killer by Oyinkan Braithwaite, Lost Children Archive by Valeria Luiselli, An Orchestra of Minorities by Chigozie Obioma, and Lanny by Max Porter.
