I used to love Gothic fiction, so I reread My Cousin Rachel and Rebecca (both by Daphne du Maurier) at least 3 times between my teens and early 30s. At first, I was drawn to the thriller/mystery aspect, as well as the moral ambiguity of the characters. Later on, I became more aware of feminist readings of the text, namely how the heroines were limited by women's gender roles at that time. Each reading opened up new layers of meaning.

Lately, I've been gravitating more towards comfort reads. I probably read The Storied Life of AJ Fikry 3 times in the last 5 years. It's a good reminder that "it takes all kinds to make a world". The main character starts out as a curmudgeon, but he still has people who love him and who soften his rough edges.
