Charlotte spends most of her time alone. Known as a know-it-all nerd, she stayed in the library and that was the way she liked it. Until a substitute librarian enters her life. Mr Styles, a tall, handsome teacher and a bit of a nerd himself takes quite an interest in her. The two become very close. Boundaries are crossed, rules are broken and love blossoms. They know it's wrong but it feels so right.
