History teacher Madison Keibler is aloof, uptight, prim and proper—and Toby Moreland’s unlikely obsession. He doesn’t understand why the newest staff member at their private high school intrigues him, he only knows he has a burning need to loosen her severe bun, strip her of those dowdy schoolmarm clothes and dirty her up a bit. As the shy, naïve Mad becomes his own personal bad girl, she quickly goes from the woman he can’t stop touching, to the woman he can’t live without. A sheltered only child raised by cold, scholarly parents, Madison’s been a student most of her life. Now Toby’s giving her the education she never knew she was missing. And not just sex, though his expertise in that area could fill volumes. He’s given her dozens of new experiences, from the joys of a simple walk on the beach at sunset, to the excitement of live sports, to what it’s like to be part of a big, boisterous, loving family. For the first time in her life, she’s living in the moment and loving every second. But the ultimate experience for both may be sacrifice, after a single careless second threatens to destroy their new, crazy, unexpected mad love.
