In the wake of her father’s death, Rose Newlin finds solace in her work as a book restorer. Then, one rainy Connecticut afternoon, a struggling painter appears at her door. William Lomazzo brings with him a 16th-century treatise on art, which Rose quickly identifies as a palimpsest: a document written over a hidden diary that had purposely been scraped away. Yet the restoration sparks an unforeseen challenge when William --- a married man --- and Rose experience an instant, unspoken attraction. Soon they are forced to confront the reality of their own mystifying connection.
