I'm curious what everyone's comfort book is!

My current one is A Lady's Guide to Scandal by Sophie Irwin. It's just a sweet, fun little novel that brought me so much enjoyment when I read it. I've gone back to it a couple times just to read my favourite parts.

It’s 2060, the entire world is looking like all those dystopian societies in all my fav books. Just a straight mess. Ereaders stopped being made decades ago but someone you love finds one for you with only a couple scratches, and even a charger, that can hold about 20 books in its memory. How do you fill this ereader? It can only be filled once.

Pick 1: (for science purposes ofc) -10 of your favorite books of all time & 10 books you’ve never read -5 of your favorite books and 15 new ones -20 new books -all 20 are books you’ve read and consider your absolute favorites

Feel free to explain ur reasoning (for science). And or the books you pick if you wanna get that specific.
