Cassandra in Reverse by Holly Smale is a Groundhog Day-type story in which Cassandra desperately tries to fix a botched relationship.
In one day, Cassandra is dumped, fired and on the verge of being kicked out of her apartment. Added to this is her parents’ death ten years earlier. Her autism makes it very difficult for her to interact with others “normally.”
She sets about fixing things once she realizes that she can rewind time (within a few months) whenever she desires. After countless attempts to control outcomes, she realizes that some things are unavoidable while others change more subtly. It becomes apparent that her gift for time travel is to repair a family relationship and to figure out herself.
There is some humor and plenty of repetition to understand the characters along with countless references to Greek mythology (one of Cassandra’s profound interests).
