Subscription box services generally are booming. For a fee, these companies will send you a monthly, curated selection of maker games, dog treats, craft supplies — you name it. And one of the strongest categories in this growing market is book boxes.
If you're into mystery novels, there's a box for you. Fantasy? Romance? YA? You're in luck. There are also boxes aimed at specific age groups — for teens, middle schoolers and toddlers. And it's not just books. The boxes often come filled with character merchandise, notebooks, bookmarks and other book-inspired gear.
