I like the suggestion of reading a group of genre books such as feminist gothic.
Recently I've been trying to read a couple of books by a particular author and then a biography or autobiography, or even a fictional book based on a true event and then a couple of factual books about the event or biographies of people involved in it.
If you want to include some poetry I can recommend Danusha Lameris. I think her poetry is wonderful, it's thought-provoking, relatable, but also brings me something new.
I am also at the moment trying to buy and read 'banned' or 'cancelled' books and authors. I've got quite a collection already and I've got to say it's bringing me into contact with books, subjects, and authors I probably wouldn't have tried otherwise.
It's a mixture of fiction and non-fiction, all fairly recent books, and I'm not necessarily in agreement with the authors or the subjects, but it's certainly making me think, and quite often it's making me do more research, examine my own opinions and pre-held prejudices etc.
The reason I started is that regardless of whether I like a book or agree with the author, I do not like the idea of banning books, cancelling authors, or putting certain topics 'off-limits' to one author but not another.
I tend to print off or cut out articles or write a small note to explain what brought a book to my attention, to keep with the book, and do a bit of research around the author or subject as well.
