‘easy 2 read // for younger ages’ has books that have short words, phrases and paragraphs and are thus easy to read. the recommended age ranges for these differ from book to book,, but it's around 1 - 5. but ofcourse you can read them at any age you regress to ! just look through the names and the covers and look at what interests you

‘hard 2 read // for older ages’ have pages full of text, thus hard to read. theyre for ages 6 - 8 and up ( if i go by the recommended age range for the pixie trick books ). but yet again, if you wanna try reading them while you're younger, you can always try ! and well,, like i said, 6 - 8 and up so even if ur older, you can still read them

‘information books to learn’ is like a sub category to the hard 2 read one, because they contain pages of text too. but ! these arent novels, and they're more specifically learning books about sharks, vampires and the solar system, with lots of facts in them !!!

the other two are harder to read, with like pages full of text. theyre for ages 7 and up ! but theyre still kids book so the text is all big and the story is easy to follow,, with easy words and all
