The Rumball Rumba by Bonnie Edwards

At Christmas, a secret baby arrives in Dickens…

Pregnant and divorced, successful artist Trix Warden returns to Dickens to raise her child surrounded by family. To do that, she needs to renovate a horse barn into a gallery/market for other artists.
At 37, her baby is an unexpected miracle that is hers alone. Determined to get everything done before Delivery Day, she hires widowed single father, Jon Carpenter to do her renovations.
As they move through the work, they spend time together enjoying the holiday season. Trix helps Jon through tricky times as a parent of teens, and he offers support throughout her pregnancy.
Their friendly business relationship blossoms into mutual attraction, and on Christmas Eve, when the baby comes early, Trix trusts Jon with her secret and her heart. But the secret Trix reveals creates a deep divide between them as Jon struggles to accept the decision Trix has made.
