SoaH Book 3: The Gathering Darkness

READ THE PRECEDING BOOKS FIRST! The forsaken storm has risen, the gathering has begun and the Camps prepare for war once again. This time though there is no Titanic force or Giant's leading pitched battle. The enemies are their own siblings. As Percy and Thalia recruit exceptional Half-Bloods for a war on the Gods they are by far the deadliest enemies Olympus will ever face.
