While attending her best friend Sashy's wedding, Flora Scurrison realizes that this monotonous, nine-to-five, cookie-cutter life is exactly what's in store for her. While it might be okay for Sashy, it's certainly not what she envisioned for herself when she was sixteen. So when her boyfriend proposes to her during the reception, Flora makes a wish to go back and do it all over again. The next morning she wakes up to find that she has been given the ultimate second chance--she's sixteen again. As Flora navigates school, first loves--new and old--and discovers what it really means to make adult choices, will she stay in her new body or try and find her way home?
