The perfect assistant, Jessalyn Palmer is proud to work for Dr. Wilbur Stieran, a brilliant mechatronic scientist and world-renowned inventor. However, when her two years of flawless service is ruined by an unfortunate spelling error, Jessa finds herself over the boss' knee. A week later, Jessa is still trying to come to terms with the spanking and the conflicting feelings the punishment invoked. Embarrassed by her response to his loving discipline, she has avoided her boss as much as possible. Then the apprentices beg her to test drive Stern Stieran's latest invention—his precious prototype, AllSPANC. By the end of the journey, Jessa (the no-longer-perfect assistant) discovers that some mistakes are worth making, and that some lessons are worth learning the hard way.
