The Music of Marcus

When Carrie Arnold's only son, Jonathan, received a diagnosis her husband wasn't equipped to handle and he left her, she thought the melody of her life had been rendered permanently discordant. For twelve years she's single-handedly kept a stable environment for her son. At forty-four, she's resigned herself to being single. She's proud of the strength and independence she gained through her struggles, but when a hit and run accident sends Jonathan into a coma, she discovers her strength may not be enough.
During the tense weeks of Jonathan's hospitalization, Carrie begins to rely on his handsome physiotherapist, Marcus, as her friend?and then more. She's attracted to him in ways that feel completely inappropriate under the circumstances. And worse, she hasn't been exactly honest with him about Jonathan's limitations. Could a younger man really contemplate changing the tune of her lonely life, or is Carrie hearing music where none exists?
