Past Perfect Life By Elizabeth Eulberg

Small-town Wisconsin high school senior Allison Smith loves her life the way it is-spending quality time with her widowed father and her tight-knit circle of friends, including best friend Marian and maybe-more-than-friends Neil. Sure she is stressed out about college applications . . . who wouldn’t be? In a few short months, everything’s going to change, big time.
But when Ally files her applications, they send up a red flag . . . because she’s not Allison Smith. And Ally’s-make that Amanda’s-ordinary life is suddenly blown apart. Was everything before a lie? Who will she be after? And what will she do as now comes crashing down around her?
