Years later, successful author Celia Cavalotti is still mourning the death of her favorite teacher, who died in a car crash in 1989. But when a car accident of her own hurtles her back in time to the week of his death, she has a chance to change the future. Finding herself in the 1980s is a shock to the extremely modern Celia-- but even more shocking is seeing her dead English teacher, Alan Forrest, alive and well before her very eyes. Alan is far more handsome than she remembers, and she can't resist the urge to flirt. After all, they have so much in common, like writing and a shared love of science fiction. Celia knows she's falling in love with him-- but can she use this opportunity to prevent his tragic death? What is happening to her? And why can't she seem to stay in one place and time?
