What happens when a tsunami rips your son from your arm, drowns him and his brother and father and grandparents, and spares your life? Wave is the author’s sobering account of years of stunning grief — a la The Year of Magical Thinking but multiplied, dementedly so, by the magnitude of the loss. The author speaks movingly of her sons’ early years, of their messes and their joys, of the spaces in their home in which she cannot live. This is a slim book with massive suffering. It would have been more powerful, for me, in a shorter form.
