Since you're specifically trying to write—a book, I guess—it may be worthwhile trying to find an app designed for that. A quick search came up with Draft (https://draftin.com/) and Reeday Book Editor (https://reedsy.com/write-a-book). I haven't used these myself, so take a look around. Source: over 1 year ago
