A lot of the time when I see books recommended for ghibli fans they feel very focused on the cute, cosy and whimsical – usually inspired by totoro, kikis delivery service, howls moving castle etc. but personally, I associate ghibli with a lot more serious themes (alongside the wholesome ones). Themes like war, death, philosophy, grief, and morality. I feel like no one is able to combine these themes better than Miyazaki, but I would love to hear some recommendations that come close!
