FBReader has always worked well for me.
Have you read, Antarctica by Kim Stanley Robinson? The book is science fiction, but covers Shackleton’s story as a motif.
I’m reading To Sleep in a Sea of Stars by Christopher Paolini. It is a lot of fun so far. The characters are deep and believable. The plot is complex and interesting. I love it!
I just finished Whalefall by Daniel Kraus if you are looking for a gripping, hard-science, scuba survival thriller. The ending is so metal. The writing is great and the tension makes it hard to read and hard to put down.
My audiobooks are clippy on Hoopla, but not anywhere else.
Clippy audio is not fun.
