Merry and the Gentleman by Donna K. Weaver

How do you choose between your heart and your responsibilities?

Merry Hurst, a fierce widow and single mom, is determined to give her young son the life he deserves—including a male role model who will stick around for the long haul. She can’t afford to fall for a man who isn’t planning to stay in Huckleberry Falls, so she might as well stop dreaming about Carlisle Wyndham. If only it were that easy!
Carlisle Wyndham is determined to develop the avalanche-proof transceiver that could have saved his wife’s life. He’s glad his daughter has made a new friend, but they’re only staying in Huckleberry Falls long enough to complete the project. When he meets the young boy’s mother, Carlisle’s not prepared for how alive she makes him feel.
But he has pressing responsibilities pulling him back to England while Merry’s require her to stay. Do they dare risk getting involved only to say goodbye?
