The title of this richly textured book derives from two of the three mysterious letters left by Emily Dickinson--the ones addressed to "Dear Master." Lucie Brock-Boido has imagined a series of letters echoing devices found in Dickinson's own work. "We feel we are in the presence of something entirely new, " says Bonnie Costello in The Boston Review. "Not even Brock-Broido's wonderful first book, A Hunger, prepares us for this bold encounter."
