When Henry Atherton helps Mr. Fogarty clean up around his house, he expects to find a mess and a cranky old man; what he doesn't expect to find is Pyrgus Malvae, crown prince of the Faerie realm, who has escaped the treacherous Faeries of the Night by traveling to the human world through a portal powered by trapped lightning. An egomaniacal demon prince, greedy glue factory owners Brimstone and Chalkhill, and the nefarious Lord Hairstreak, leader of the Faeries of the Night, all dream of ruling the Faerie realm and are out to kill Pyrgus. Enlisting the help of his sister, Holly Blue, and his new friend, Henry, Pyrgus must get back to the Faerie world alive before one of his many enemies gets to him instead. But how many portals are open, and can Pyrgus find the right one before it falls into the wrong hands? Conjuring scenes filled with vivid color, unforgettable detail, and fearless characters, author Herbie Brennan brings readers to the Faerie world, where nothing is ever what it seems and no one can be trusted.

When Henry Atherton returned to his own life in the suburbs of London, he thought all was well in the Faerie Ream. His new friend Pyrgus, the crown prince of Faerie, was about to be coronated as Purple Emperor. But then Princess Holly Blue arrived on Earth, seeking Henry’s help once more. A plot to assassinate Pyrgus is afoot, but that’s not the worst of their problems. Pyrgus’s father, the murdered Purple Emperor, has been raised from the dead by means of foul necromantic sorcery. Now Lord Hairstreak and the sinister Faeries of the Night have seized control of the Realm . . . and driven Pyrgus and his allies into hiding. Henry has no choice to return to the world of Faerie to aid his friends. But that proves easier said than done when the mystical portal linking their realms goes awry. Now Henry will have to scramble just to stay alive in a fantastic world that’s constantly full of surprises . . . and danger.

It is Henry's third visit to the Faerie Realm, but this time in a rather different guise and to a different kind of place. Holly Blue is Queen and Lord Hairstreak appears to be proposing a truce between the Faeries of the Night and the Faeries of the Light. Meanwhile, Prince Pyrgus has stumbled across some mysterious crystal flowers with an apparently formidable secret weapon, and there are rumours of a demon invasion led by Beleth, the Prince of Darkness. Queen Blue, wary of her uncle's uncharacteristic generosity, pays a visit to the Spicemaster's labyrinth in an attempt to divine the possible future of the Realm. She is warned to beware of someone close, not realizing just how careful she will need to be—and when she is kidnapped by the most unlikely candidate, the Realm rapidly descends into chaos. In a thrilling adventure Blue, Pyrgus and Henry will find themselves in the midst of a furious battle to protect the future of the Realm and secure the throne for the rightful ruler.

Henry has all but forgotten the Faerie Realm since he returned to his normal life two years ago, but now his past has followed him home. Out of nowhere, Henry's old friend Pyrgus appears-looking like a middle-aged man-and his life is turned upside down once more. Determined to help his friends, Henry returns to the Realm, hoping to find a cure, and perhaps win his way back into the heart of Queen Holly Blue. But what Henry, Pyrgus, and Blue don't know is that the plague is hardly an ordinary disease...

When you're the daughter of faerie royalty - born and raised in a faerie palace, with a kingdom's worth of magic at your fingertips - what kind of place could possibly seem exotic? The human world, of course! And that's exactly where Princess Melia is headed. All she has to do is cast a spell on her parents, King Consort Henry and Queen Holly Blue, to make them forget they ever had a daughter. Anticipating nothing more than a day's outing, Mena is not prepared for a portal miscalculation that accidentally lands her in Haleklind, where she discovers rebel forces preparing an invasion using a terrifying new magical weapon. And that's not the only plot threatening the Faerie Realm. The evil lord Hairstreak has returned - though he's now an evil head in an evil box. That doesn't stop him from launching his most nefarious plan yet to gain control of the Realm - and he won't let a little thing like a princess stand in his way.

Ci credete nelle fate? Henry Atherton di sicuro no. Per lo meno è ciò che ha sempre pensato, ma ora se ne sta immobile, a bocca aperta, le palpebre che battono furiosamente mentre cerca di decidere cosa sta guardando. Poutpourri, il gatto del signor Fogarty, è convinto di aver preso una farfalla, ma non è una farfalla quello che Henry vede. Ha le ali di farfalla, d'accordo, ma per il resto... sembra proprio una fata! E Pyrgus Malvae non è una fata qualsiasi, è un principe ereditario giunto nel Mondo Analogo (che poi sarebbe il nostro) attraverso un antico portale per volere di suo padre, il Re degli Elfi. Pyrgus, infatti, si è messo nei guai: Lord Rodilegno vuole la sua testa perché gli ha rubato una fenice, mentre Bombix e Sulfureo intendono sacrificarlo a Beleth, un demone che sta mobilitando le proprie armate per annientare il Regno degli Elfi. È l'inizio di un'amicizia che varca i confini di due mondi e di un'avventura che condurrà Henry in un regno affascinate, tra furiose battaglie, diabolici raggiri, oracoli misteriosi... fino all'incontro con una bellissima principessa.
