Pauline is spending the summer at World's End, a cottage somewhere in the middle of England. This year the adjoining cottage is occupied by her daughter Teresa and baby grandson Luke; and, of course, Maurice, the man Teresa married. As the hot months unfold, Maurice grows ever more involved in the book he is writing - and with his female copy editor - and Pauline can only watch in dismay and anger as her daughter repeats her own mistakes in love. The heat and tension will lead to a violent, startling climax. In Heat Wave, Penelope Lively gives us a moving portrayal of a fragile family damaged and defined by adultery, and the lengths to which a mother will go to protect the ones she loves.
