The Part-Time Wife — Maureen Child

At some point during the time Luke Talbot arrived late at the high-society soiree, then hurried her home for safeguarding, Abby realized her husband truly was living a double life. His secrets, however necessary, tore at her insecurities. How could she have married this man, slept in his arms, given him her heart...never knowing who he truly was?

His lies left her no choice. She filed for divorce.

And discovered that Luke wasn't about to let her go without a fight.
