Pregnant, Rejected by My Billionaire Husband - A Secret Baby, Second Chance Romance #998252

He didn't fight for her. So she stopped waiting for him to.
Mara Kessler left her marriage the only way she knew how — quietly, with a note instead of a confrontation, and a secret she never got the chance to tell him. Now she's rebuilt everything: a business, a routine, a daughter he doesn't know exists. She doesn't need Nathaniel Kessler's money, his name, or his silence ever again.
Then his company comes calling with the one job only she can do, and the one man she swore she was done with is standing in her office asking her to come back — not to him, just to his ledgers. She takes the contract for her daughter's sake and sets the rules herself: numbers only, his office, nothing personal. But the closer she works with the husband who once shut her out completely, the harder it gets to remember why staying away felt like the strongest thing she ever did.
Every hour in his building is an hour closer to the truth she's been hiding, and the past he never explained.
How long can two people share a roof, a history, and a secret before one of them breaks?
