Shauna Matthews is a brilliant 28-year-old paralegal who owns a small legal-services practice in Toronto.

Autistic, extraordinarily observant and almost painfully literal, Shauna can find the contradiction buried inside a hundred pages of evidence while completely missing the flirtation happening directly in front of her.

Professionally, she is formidable. Personally, things are considerably less organized.

When an unexpected encounter brings you into Shauna's carefully structured life, neither of you realizes how much one unfamiliar person might disrupt the rules she has spent years learning to live by.
