Mercury: A Novel of Marriage, Obsession, and Desire That Changes Everything

A Seattle Times Best Book of the Year • A BookPage Best Book of the Year • A Kirkus Best Fiction Book of the Year

The New York Times bestselling author of “brilliantly paced contemporary adventure” (Elle) delivers her most gripping novel yet—at once a tense, psychological drama and a taut emotional thriller about love, obsession, and the deceits that pull a family apart.

Donald believes he knows all there is to know about seeing. An optometrist in suburban Boston, he is sure that he and his wife, Viv, who runs the local stables, are both devoted to their two children and to each other. Then Mercury—a gorgeous young thoroughbred with a murky past—arrives at Windy Hill and everything changes.

Mercury’s owner, Hilary, is a newcomer to town who has enrolled her daughter in riding lessons. When she brings Mercury to board at Windy Hill, everyone is struck by his beauty and prowess, particularly Viv. As she rides him, Viv begins to dream of competing again, embracing the ambitions that she had harbored, and relinquished, as a young woman. Her daydreams soon morph into consuming desire, and her infatuation with the thoroughbred escalates to obsession.

Donald may have 20/20 vision but he is slow to notice how profoundly Viv has changed and how these changes threaten their quiet, secure world. By the time he does, it is too late to stop the catastrophic collision of Viv’s ambitions and his own myopia.

At once a tense psychological drama and a taut emotional thriller exploring love, obsession, and the deceits that pull a family apart, Mercury is a riveting tour de force that showcases this “searingly intelligent writer at the height of her powers” (Jennifer Egan).
