Teresa's Tattoo

The story

Mathematician Teresa just wanted to study during the College spring break. But her friends, who want her to live a little, drag her out to parties. The next thing she knows, she has been drugged, kidnapped, made a redhead, tattooed, and wearing leather?!? Her captors seem to be the most inept crooks ever. They seem to have a plan, if only she could figure out why it involves her.
