A Forrest for the Holidays by Erin Marie Bassett

Book 1 in the Howdy Holidays Series

A Forrest for the Holidays is a spicy, cowboy, Christmas romcom featuring a reluctant rancher, an out of place actress, and a meddling highland cow. It's a story about two people learning to understand the world and finding their place in it together.
