"Often funny, always lovable, this endearing novel of obsessive compulsive disorder and romance is outstanding."
--Boston Globe





An absolutely delightful tale of obsessive-compulsive love, Toni Jordan's Addition is just the ticket for fans of TV's Monk and readers who were captivated by The Curious Incident of the Dog in the Night-Time. A wonderfully funny, supremely intelligent debut novel, Addition is "witty fun" (People), while OCD-afflicted heroine Grace and her new-found paramour Seamus are "thoroughly endearing characters, and their romance is sweet and fun" (Washington Post Book World).
