Pre-owned, like new condition, only read once. Only the first book has visible signs of use (see photos) but the rest are in basically pristine condition. Such a fun series for middle grade readers who love Greek mythology! I would prefer to sell these as a bundle rather than individually. I have priced them higher because you can no longer buy these new from Amazon. Make me an offer! Comes from a smoke-free, pet-free, odor-free home. Item arrives clean and neatly packaged. Shipped with care! Message me for bundles or if you have any questions/offers!
