Rainbow's Promise — Marcy Gray

Marriage motives...

Lily Ann Jones: Revenge drove her to find Joshua Delaney. Compassion moved her to help him. She'd tracked down her father's sworn enemy only to find a man who'd been terribly wronged.

Joshua Delaney: Gorgeous, single, struggling to raise two children -- and blind. His new housekeeper, Lily, seemed an answer to a prayer, an angel of light who'd arrived on his doorstep at just the right moment.

Marriage motives: Joshua needed a wife to keep his niece and nephew in his care. Lily needed to uncover the secrets of the past -- even if it meant loving a man who would someday despise her.
