Fun time-travel story. Lissy travels back to 1991, to her junior year at Lyons Township high school. She was the mean girl, but now she's going to right some wrongs. By the end, she learns some truths about herself, her life, and Nirvana. Not everything makes sense, and she has to go back a few times, but it's fun if you go with it. I enjoyed the 90's references.
