Heart on a String — Carla Neggers

Witty, unconventional JoAnna Radcliff fell off a ladder into brilliant heart surgeon Paul Houghton Welling's arms. But one look at him told her he belonged in the stuffy Philadelphia society world she'd escaped for a cottage in Pigeon Cove. She firmly believed she'd never fit into his life -- she, a puppeteer, spent her days in paint-spattered jeans and her evenings in antique dresses from her grandmother's attic.
But she couldn't have been more wrong about Paul -- and he set out to show her, with infinite patience and fierce determination. She was the puppet master, but he knew how to keep her heart on a string.
