Local hero - Nora Roberts

Who was that masked man...? When Mitch Dempsey appeared in Hester Wallace's doorway bearing gifts, she knew she should beware. She'd just moved and didn't need trouble in the form of an all-too-attractive downstairs neighbor. Her nine-year old son had no such qualms. When he discovered Mitch was the creator of his favorite comic book here, he was sold.
Though Mitch was no Superman, Hester made him feel he could leap tall buildings in a single bound. But could he convince her she needed a hero to call her own?
