Lariviere, Sarah. Time Travel for Fun and Profit. Penguin, 2021.
For the most part, Time Travel for Fun and Profit is a standard Young Adult romance. A smart high school freshman has a hard time making friends and longs her first kiss, a la Princess Diaries. But she is a math whiz who has created a powerful AI app on her cell phone. The app gets smarter each time she uses it to time travel so she can repeat her disastrous freshman year. But it is not the total Groundhog Day event. She is in a time loop where everyone but her ages, though no one, including her parents, remember that this is the second time around. They all have holes in their memories. The book is a little better than all this makes it sound. 3.5 stars.… (lisätietoja)

Nephele Weather's best friend Vera drops her without a goodbye in their freshman year of high school, so Nephele - a math prodigy - decides that the best and easiest course of action is to build a time machine and go back to fix what went wrong. For Nephele, though, math is easier than interpersonal relationships: without Vera, her best friend is a photograph called Chicago, 1955, by Harry Callahan, that hangs on a wall in her parents' bookshop. Nephele codes a timeship and successfully travels back in time - but she realizes that she's erased her parents' memories of their past year; there are "black holes" in their brains. No matter, Nephele can just fix the code, go back in time again, and fix it...

Time after time, Nephele repeats her freshman year, talking through her "thought experiment" with a science teacher, until at last she makes friends - Jazz, Rex, and Airika - who make her think differently, not just about code but about the true best way forward.
