"Pyrgus, Henry, and Blue thought they'd defeated their enemies Brimstone, Hairstreak, and Chalkhill. But when Henry finds himself on the other side of the Blue Fire Portal and back in the land of Faerie, he learns the once-murdered Purple Emperor has been resurrected and the Faeries of the Night are using him to control the entire Faerie Realm. Formerly Crown Prince, Pyrgus is heir to the throne no longer, and Comma, his mysterious younger brother, has control. Or does he? Banished to far-off lands, stripped of any power they might have had, and without anyone to help them, Pyrgus and his fearless sister Blue must fight their way back to the palace to retake what is rightly theirs. But Hairstreak's determination to maintain complete power through deception, disguise, and other disgusting methods creates havoc that none of the young heroes could have predicted."--Publisher's website.
