Book Recommendations related to Moomin

Hi! I used to love reading years ago, but school killed my passion for it. I'm wanting to start over again for the new year. Are there any books that would be good to read that are like the vibes and adventures from Moomin, Animal Crossing, Sims, Studio Ghibli, etc.? Sorry this is broad but I think I'm looking for something fun to read, TIA!:-)
