(5/50$) Rick Riordan The Trials of Apollo Book Set from the Percy Jackson verse

Complete set of The Trials of Apollo series. Includes the first 3 books of the series + a free sampler presenting 3 other books. The events of this series would be right after Heroes of Olympus if anyone is trying to follow the chronological order of the Percy Jackson lore! The books are in great condition, albeit rather dusty. The box has some whitening on the corners, but all are in very good condition. Please feel free to bundle 5 of my listings marked with (5/50$) and get all 5 for 50$!!
