A QUIET ADJUSTMENT, by Benjamin Markovits (Norton, $14.95.) ''I fear very much you will find out you have married a devil,'' Lord Byron confides to his new wife, Annabella Milbanke, at the start of their honeymoon -- and she does. This eloquent novel, the second in a proposed trilogy, is presented in a third-person narration that seems to arise from Annabella, a beautiful 19-year-old. Her perspective is conveyed with a hesitant formality reminiscent of Henry James, and ''phrase after phrase winks for readerly attention,'' our reviewer, Jay Parini, said. REBORN: Journals and Notebooks, 1947-1963,by Susan Sontag. Edited by David Rieff (Picador, $15.) These notebooks -- two more sets are planned -- open when Sontag is 14, and take her to the brink of success. Rieff, her son, writes in a moving preface that he would have preferred not to release this material but did so only because Sontag's papers had become public on her death in 2004. From the beginning, Sontag appears serious and dedicated to high culture, and although she is self-absorbed, events like her marriage and the birth of her son pass almost without mention.
