The Second Wife of Reilly

A spin-off of Coburn's debut novel, The Wife of Reilly, her holiday novella, The Second Wife of Reilly takes readers into the world of Sarah Peterson, who is spending her first Christmas with her new husband. 

With her life finally in order, Sarah should be happy, but she has nagging doubts about her new marriage to nice guy, Reilly.  He's a gem, but  she'd feel a lot more comfortable if his first wife, Prudence had a new man in her life.  If Reilly's first wife were off the singles’  market there would be no chance of her coming back for a reconciliation. 

That's when Sarah decides the best way to chase away the holiday blues is to find a new husband for Prudence.  After all, wasn't it Prudence who placed a singles' ad for Reilly and dated women, trying to find her own replacement?  Payback's a bitch.
