Affairs to remember. You won’t soon forget these novels involving infidelity.

1. The Girl on the Train by Paula Hawkins

“Rachel takes the same commuter train every morning and night. Every day she rattles down the track, flashes past a stretch of cozy suburban homes, and stops at the signal that allows her to daily watch the same couple breakfasting on their deck. She’s even started to feel like she knows them. Jess and Jason, she calls them. Their life—as she sees it—is perfect. Not unlike the life she recently lost.

“And then she sees something shocking. It’s only a minute until the train moves on, but it’s enough. Now everything’s changed. Unable to keep it to herself, Rachel goes to the police. But is she really as unreliable as they say? Soon she is deeply entangled not only in the investigation but in the lives of everyone involved. Has she done more harm than good?”

2. This Is Where I Leave You by Jonathan Tropper

“The death of Judd Foxman’s father marks the first time that the entire Foxman clan has congregated in years. There is, however, one conspicuous absence: Judd’s wife, Jen, whose affair with his radio- shock-jock boss has recently become painfully public. Simultaneously mourning the demise of his father and his marriage, Judd joins his dysfunctional family as they reluctantly sit shiva and spend seven days and nights under the same roof. The week quickly spins out of control as longstanding grudges resurface, secrets are revealed and old passions are reawakened. Then Jen delivers the clincher: she’s pregnant.

“This Is Where I Leave You is Jonathan Tropper’s (One Last Thing Before I Go) most accomplished work to date, and a riotously funny, emotionally raw novel about love, marriage, divorce, family, and the ties that bind-whether we like it or not.”

3. Made To Break Your Heart by Richard Fellinger

“A family saga, set in a gossipy suburb, that explores the complexities of raising a child, holding a marriage together, and maintaining your sanity in the cutthroat world of Little League baseball.

“It’s 2008, and Nick Marhoffer is a stressed-out dad who finds himself flirting with thoughts of infidelity. While his job is being threatened by a crumbling economy, he’s fraught with anxiety over his only son’s well-being. So when his son starts playing baseball, Nick becomes a rabid Little League dad who loses sight of what’s good in his life. After developing a crush on a gorgeous team mom, he can’t decide between her and his wife, then finds himself at risk of losing everything that’s most important to him.

“This is a smart, sexy, and funny novel about bad breaks, bad decisions, and the long road of life.”

4. The Silent Wife by A.S.A. Harrison

“Jodi and Todd are at a bad place in their marriage. Much is at stake, including the affluent life they lead in their beautiful waterfront condo in Chicago, as she, the killer, and he, the victim, rush haplessly toward the main event. He is a committed cheater. She lives and breathes denial. He exists in dual worlds. She likes to settle scores. He decides to play for keeps. She has nothing left to lose. Told in alternating voices, The Silent Wife is about a marriage in the throes of dissolution, a couple headed for catastrophe, concessions that can’t be made, and promises that won’t be kept. Expertly plotted and reminiscent of Gone Girl and These Things Hidden, The Silent Wife ensnares the reader from page one and does not let go.”

5. Anna Karenina by Leo Tolstoy

“Considered by some to be the greatest novel ever written, Anna Karenina is Tolstoy’s classic tale of love and adultery set against the backdrop of high society in Moscow and Saint Petersburg. A rich and complex masterpiece, the novel charts the disastrous course of a love affair between Anna, a beautiful married woman, and Count Vronsky, a wealthy army officer. Tolstoy seamlessly weaves together the lives of dozens of characters, and in doing so captures a breathtaking tapestry of late-nineteenth-century Russian society. As Matthew Arnold wrote in his celebrated essay on Tolstoy, ‘We are not to take Anna Karenina as a work of art; we are to take it as a piece of life.’”
