雷克．萊爾頓《太陽神試煉 》 All five books in the best-selling Trials of Apollo series are now available in a paperback boxed set complete with a bonus poster. Rick Riordan's beloved Greek and Roman demigod characters from Percy Jackson and the Olympians and the Heroes of Olympus return in a five-book adventure quest with a fresh twist: they’re helping Apollo regain his immortal status. Apollo's fast-paced, monster-filled quest brings the Percy Jackson chronicles to an end. Now readers from 8 to 80 can enjoy it from start to finish and then keep the handsome box on their shelf for posterity. Also included is a bonus poster of the key locations and characters in the series.
