Hamnet is a novel inspired by the son of a famous playwright. It is a story of the bond between twins, and of a marriage pushed to the brink by grief. It is also the story of a flea that boards a ship in Alexandria; a kestrel and its mistress; and a glovemaker's son who flouts convention in pursuit of the woman he loves. Above all, it is a tender and unforgettable reimagining of a boy whose life has been all but forgotten, but whose name was given to one of the most celebrated plays ever written.
