The exciting quest adventures featuring modern-day demigods and ancient monsters that Rick Riordan introduced in the Percy Jackson and the Olympians series are far from finished. Memorable characters (including Percy himself), witty dialogue, and non-stop action abound in this second Olympian series, which spans the United States, Europe, and even the underworld. Now all five books in the Heroes of Olympus series are available in a paperback boxed set of heroic proportions. From The Lost Hero to The Blood of Olympus, this collection will thrill loyal fans and be a go-to gift for readers new to the internationally best-selling series. Includes a stunning poster of the seven Greek and Roman demigods who form the Prophecy of Seven.
