Christmas on 4th Street / Susan Mallery.

Enhanced descriptions from Syndetics:

There's nowhere better to spend the holidays than with New York Times bestselling author Susan Mallery in the town of Fool's Gold, where love is always waiting to be unwrapped... Noelle Perkins just got a second chance at life, and she intends to make the most of every minute. That's why she ditched a frustrating legal career to open her own store in Fool's Gold, California. The Christmas Attic celebrates everything that's magical about her favorite season. Business is booming, and as a bonus, gorgeous army doctor Gabriel Boylan has offered to help out during the holiday rush. Gabriel's memories of Christmas past contain more sour grapes than sugar plums, thanks to a drill sergeant father who ran his home like a boot camp. Spending the holidays with his family while he recuperates from injury sounds as appetizing as last year's eggnog. Still, there are some enjoyable distractions in town, including sunny, sexy Noelle...and the red-hot mistletoe kisses they can't stop sharing. Gabriel didn't think he was made for happily-ever-afters. But when fate hands you a love as sweet and surprising as this, only a fool could refuse....
