Liz Bennett knows that she is one of the lucky ones. She's married to a wealthy and charming man who is a supportive husband and a doting father. A rising banker at a top firm in Boston, Arno is the picture of perfection, rounding off their idyllic New England life. But when Liz sees a suspicious text with a kissy-face emoji on Arno's phone, her anxiety kicks into overdrive and she begins to worry that her luck has just run out. The days that follow are plagued by persistent skepticism and countless sleepless nights until Liz decides she must uncover the truth about her husband and this suggestive text. But as she peels back layers of deceit and tracks down every lead, a frenzy begins to take over her life. Could Arno really be unfaithful? Or is Liz's imagination getting the best of her? Witty and, at moments, brooding, Justine Sullivan's debut explores the nuances of a new mother's vulnerability when everyone around her is convinced she's become unhinged. And as the validity of the life she once knew unravels page by page, Liz must prove, if only to herself, that a woman's intuition expands beyond one cryptic text message.
