Newfound Love by Kay Brooks

Miranda “Randi” Cavanaugh is a successful interior decorator with twin six-year old sons, Scott and Sandy. A busy single mother, she is also best friends with Ginny, Brina and Marcie who have partnered with her to renovate an old firehouse into a business complex in their small town. Randi has yet to meet their contractor and always arrives for meetings in time to see him walking away.
Trevor Graystone is Randi’s elusive contractor. He is also the owner and developer of Snowridge Mountain Resort where through a series of mistaken identities, the two finally meet. Both are immediately smitten with one another.
Randi’s life is turned upside down when her ex-husband Tim Cavanaugh and his new wife suddenly show up at the resort. Memories of her turbulent marriage haunt her when Tim hints that he wants joint custody of the boys. Suddenly Randi’s life is an open book.
It also seems someone doesn’t want the firehouse renovated. The harder they work to complete the project, the more it is sabotaged and Randi and Trevor wonder if it is jinxed. Unbeknownst to everyone, the firehouse is tied to a mystery that occurred ten years earlier.
