My Sister’s Secret Baby with My Husband - A Marriage Secrets and Betrayal Revenge Romance #987686

The baby's eyes were the precise shade of grey-green that Sera had spent eleven years waking up next to.
She was standing in her estranged sister's bathroom at the baby shower — champagne flute in hand, a photograph on the shelf — and she understood in the space of a single breath, completely and irreversibly, what she was looking at.
She went back downstairs. She ate a miniature quiche. She spoke to a woman named Cressida about dry-cleaners.
She did not say a word.

What Sera Calloway did instead — over the next ninety days, with the methodical precision of an architectural historian trained to find what was hidden inside walls — was build the most complete and devastating case she had ever assembled. A hotel receipt folded into careful thirds. Twenty-three entries in an encrypted document. Photographs taken in nine minutes through a bathroom door. A false name on a bank account. An apartment on Vellum Street. And a message thread that ended with four words she read once and filed away:

She has your eyes.
He knew. He had always known. He had come home and put his phone face-down on the kitchen counter and asked how her day was.
She made his toast. She refilled his wine. She smiled across the kitchen table of a marriage that looked, from the outside, entirely intact.
Her hands were completely steady.
