All first edition hardcover book set for the hero’s of Olympus. 2014 Barnes and noble exclusive. Never been read, all of the books are in perfect condition. The top left on the back of the mark of Athena has a very slight bend, which is shown in the pictures. All the pages are clean with no marks. This collection has just been sitting on my shelf for many years, which is why the inside of the box has some marks. I took pictures of all the angles, but if you have any questions please let me know.
