Megan Ausia Waverly is a beautiful social media influencer and stay-at-home wife who resides in Milwaukee, Wisconsin with her millionaire husband, James Waverly. James is in the cryptocurrency business and spoils Megan financially, providing them with luxurious vacation homes in Miami and Los Angeles. Despite this, Megan has a tendency to shop recklessly and flirt with other men behind James's back, even when they are out together. She keeps a diary of her sexual escapades and feels guilty afterward but continues to cheat on her husband.
Megan's best friend, Lila Hamilton, and her social media manager, Alicia Sanders, are her closest confidantes. However, unbeknownst to Megan, a private detective named Thomas Bennett has been following her every move and documenting her infidelity. As if that wasn't enough, real estate mogul Maxwell Cunningham is also trying to seduce Megan out of jealousy towards James. But Megan is suspicious of Maxwell and never takes him seriously, thinking that someone is trying to catch her in the act by sending him.
Despite James's desire to have children, Megan always finds a reason to delay starting a family. She doesn't want the responsibility that comes with being a parent, but she knows that revealing this to James could lead to divorce. Meanwhile, she seeks solace in therapy sessions with Dr. Evelyn Brooks.
As time goes on, the tension between Megan and James rises as she continues to cheat on him without remorse. The strain on their marriage becomes unbearable, with James becoming increasingly suspicious of Megan's behavior. Eventually, everything comes to a head when James discovers Megan's diary and confronts her about her infidelity.
In the end, Megan must face the consequences of her actions as James decides whether or not to forgive her, or never let what she has been doing reach the light of day. The novel is a gripping tale of love, betrayal, and the consequences of one's actions.
