It has been four months since Conrad Morrisey's wife, Rose, has died, and the grief-stricken man has fallen into despair, forgetting even to dress or eat. Distracted by his loss, Conrad has allowed his wife's cherished garden to slip into dilapidated neglect. Yet the garden has never appeared as vibrant and overflowing as it does this season. It is in this wild, exuberantly abundant garden, that Conrad receives an unearthly visitor: an angel who appears to be his deceased father-in-law, Lemuel. Lemuel-the-angel brings Conrad an extraordinary message.

As the reticent Conrad struggles to tell his magical story to the townspeople of Laurel, he finds himself drawn out of his enclosed life of pigeon tending, and thrust directly into the hub of Rose's life in a way he'd never experienced. As the many people who've been touched by Rose make pilgrimages to the garden, he learns of his wife's incredible generosity and compassion. Conrad had thought his life was over, but buoyed by Rose's message of love, he is about to embark on vital journey of the heart.
