"One year ago, Penny was the star of her high school's theater department, surrounded by a group of misfits, and on the cusp of falling for her best friend, Wes. Now, Penny is a shoo-in for homecoming queen. Her old friends won't talk to her, Wes ignores her, and her best friend is the most popular girl in school. Penny is revered--and hated. In one year, she's changed so much that her old life is almost unrecognizable. But in a flash, a near-fatal lightning strike leaves Penny with no memory of the past year--or how she went from drama nerd to queen bee. As a record number of fireflies light up her town and her life, Penny realizes she may have the second chance she never expected--and that even if she can't change the past, she can learn to see the magic where she never could before." -- from dust jacket.
