Key to Love — Judy Ann Davis

When architect Elise Springer's father is injured, she immediately leaves San Francisco to care for him. The last person she expects to encounter in her Pennsylvania hometown is her childhood friend Lucas Fisher. Lucas is investigating his brother's mysterious death, and Elise can't resist lending a hand.

Lucas longs for the close family ties he never had. He's back in Scranton to set up a classic car restoration business and build a future. The torch he carries for Elise burns brighter than ever, but before he can declare his love, he must obtain the legal rights to adopt his nephew--and prove his brother's death was no accident.

As they unearth clues to find the murderer and a missing stash of money, Elise faces a dilemma. Is her career on the West Coast the key to her happiness, or is it an animal-cracker-eating four-year-old and his handsome uncle instead?
