I wanted so much to like this but it just never got better. It should have been right up my alley (time travel! Autistic/synesthetic main character!) but it did neither of those things in ways that worked for me. The time travel part just meant we experienced the same, inconsequential, unemotional events incessantly, while the main character bumbled around making a series of increasingly ridiculous Looney Tunes-esque mistakes every time. The bit got old after the first three times and then kept going on. Undo! Undo! Undo! GIRL STOP. She literally discovered she had the power to go back in time and chose to continue to go to work, use her ability to bend the universe to her will to attend endless meetings, write awkward emails to her boss at the job she hated, and relive her worst day ever. Impeccable decision making there.

None of the overly caricatured characters were likeable, which made it impossible to care what happened for them. It was hard to believe Cassandra even cared about her bland boyfriend because the internal monologue meant to showcase her social difficulties so often felt more like misanthropy than autism -- literally nobody was ever portrayed positively. We saw no instances of Cassandra comfortable around ANYONE or connected to ANYONE in a meaningful way. This woman actively disliked and resented everybody she encountered on a daily basis. While that may have been part of the point, it made for a depressing slog of a read.
