I'm reading three books: the obligatory Perry Rhodan (I started waaaay too late so this will take a while), a science book in my field and one book about trees by Peter Wohlleben. Additionally I am reading a Manga (Demon Slayer) - the first one that I continued without losing interest after the first few pages.
Reading all of them on my PocketBook, but I also have the books on my phone in case I'm stuck somewhere and don't have the PocketBook with me.
