Comfort book for when sick

Hello everyone! I am currently under the weather and i would like to read a book you find comforting. here is overall what i am looking for

1. no long books (not over 500 pages)
2. books that you find comforting, either because of the mood it sets (like a ghibli movie)
3. OR books you find comforting because you think they are very good reads, just no very icky themes or scenes

for reference, i liked “the secret garden” and “a man in moscow”

thank you all so much in advance!! have a good day!
