Lot of 13 books from Usborne’s Billy and the Mini Monsters collection. There are a total of 18 books in the series and I have 13 of them here! Once your child reads one, they will want to read them all! These books are in excellent used condition with no stains or writing or bended pages (dog ears). My son loved these books! Cute stories! Only flaw is one book with an outside cover slightly torn at the bottom which is in the photos. Thank you for your consideration. Comes from a clean and smoke free home. No stale or funny book smells.
