Ollie Jolson has stumbled across a secret so big no one will ever believe him. He's fallen into a world where walls can literally have ears - and eyes, and brains, and stomachs too. The despicable Lord Wight wants to take over everything and everyone, and only a couple of kids stand in his way. One of them is still in his pyjamas.

When you're lost in a space-time continuum, getting home is much harder than it sounds.

The adventure continues in this third book of the epic multiplatform fantasy series.

Erdas is a land of balance. A rare link, the spirit animal bond, bridges the human and animal worlds. Conor, Abeke, Meilin, and Rollan each have this gift-and the grave responsibility that comes with it.

But the Conquerors are trying to destroy this balance. They're swallowing whole cities in their rush for power-including Meilin's home. Fed up with waiting and ready to fight, Meilin has set off into enemy territory with her spirit animal, a panda named Jhi. Her friends aren't far behind . . . but they're not the only ones.

The enemy is everywhere.

Jack and Jaide Shield finally learn what it really means to be a warden in training as they pit their wits and their gifts against a rival - who is also a troubletwister! But as they explore the forbidden dark of the Evil dimension, they also have to come to terms with the truth about Grandma X's twin sister and face their greatest challenge ever...

When Grandma X is put out of action by an accident that may or not have been caused by The Evil, it’s up to Jack and Jaide Shield to help their father recover a lost Golden Card from Portland’s strangest landmark: The Rourke Castle.

Negotiating secret passages, talking parrots and animated suits of armour is all in a day’s work for the troubletwisters, whose Gifts are steadily coming under control. But agents for The Evil are everywhere, including one apparently masquerading as an old and trusted friend. Soon the race is on. Whoever gets the card first will gain access to a Gift more terrible than any other--if only the twins knew what it was.

Their quest takes them deep into the hidden spaces of Rourke Castle, exposing secrets kept safely from them, until now. In the process they gain a deeper understanding of The Evil, the Wardens, their father and grandmother--and themselves.

Last time, twins Jaide and Jack defeated the evil with luck and intuition. This time they must truly master their powers as Troubletwisters. The second exciting, mysterious instalment in the series, from fantasy masters Garth Nix and Sean Williams.

After The Evil's assault on Portland, everything returns to relative normality...for the moment. The twins continue to work hard to control their Gifts, and at school they make a new friend, Tara. But then the instruments in Grandma X's antique store begin registering Evil activity, and Tara's dad turns out to be the suspicious big-city property developer working on the house next door. Matters turn from bad to worse when the twins discover that Grandma's cats are fighting an important battle of their own. Can the twins solve the mystery of the living Ward before it's too late?

Twin siblings Jack and Jaide discover they are pivotal to a secret supernatural organisation that protects the earth from marauding Evil! Portland might seem like a quiet coastal town, and their grandmother is perhaps no dottier than anyone else's, but it soon becomes apparent that the strange things going on around them are anything BUT ordinary.

It's all very well discovering that you suddenly have magical powers, but when you don't know exactly what they are, or how to use them, then facing impending peril doesn't seem like a very good idea at all...

Ollie is lost. The world he came from is just one of many. Some of them are almost identical to his. Others contain cyborg pirates, living castles, talking cats - and now, hungry vampires too. Getting back home is proving surprisingly difficult.

Fleeing from the eerie Fixers, Ollie lands in a village cursed by blood-sucking neighbours. It's easy to take sides. But does Ollie choose the wrong one, this time? And if so, how can he possibly put it right?

Ollie really has his work cut out for him this time. Getting safely to the Fixers' home world is just the first step. Then he has to find out what their plan is, seal up the holes in the multiverse, and get home again, all before his parents wake up and find him gone.

Psychic typewriter - check. Telepathic TV - check. Wicked widget - check.

He needs every advantage imaginable-and all the help from himself he can get.

Eo's Castle was just the beginning of Ollie's troubles. Armed with nothing but a psychic typewriter, Ollie resumes his quest to get back home to the street where nothing works quite right, and the sinister Fixers are breaking holes in much more than the sidewalk.

Instead he finds himself on a rescue mission in deep space, fighting pirates who are more machine than human, with a cat who wishes he was human . . .

Ros is heading for the coast with Adi and Know-it-All the camel, hoping to drop the crystal containing the Golem of Omus to the bottom of the ocean.

Arriving in Samini, a small town on the outskirts of the Strand, the friends meet Quirk, who tells them outrageous stories about Ros's 'heroic' adventures. Ros doesn't suspect Quirk's treachery until he disappears - along with Varis, Adi's kinsman and bodyguard.

Ros and Adi use the Change to track Varis down, but now they're up against the Scarecrow, a lethal amalgamation of man and material who will do anything to get hold of the power contained in the crystal Ros holds.

Ros is in real danger. His family are so desperate to save their drought-stricken farm that they′ll sacrifice anything - even him - for rain. His only friend is Escher, an unseen entity with a voice that whispers in Ros′s head, continuously warning him to leave before it′s too late.

Escaping from his vengeful family astride a stolen camel, Ros decides to try his luck in the desert, discovering along the way a power he never knew he had. Through Escher, Ros learns to control the Change, a magical force that taps into the land, the water, fire and the air. He also meets Adi, a girl from a travelling clan of nomads, who asks him to save her from a future she′s desperate to avoid.

When tragedy strikes, Ros seeks help from a powerful Stone Mage, but when even she can′t save him, he starts to question everything that has happened on his journey. He must decide who is telling the truth, and who his real friends are.

Adi′s body has been borne away across the desert by her Clan, but her spirit remains Ros′s constant companion. If he can′t find the travellers in time, Adi will be presumed dead and her body cremated, leaving her a ghost forever.

But Ros is not prepared for the dangers lurking in the shifting sands. Rescued from bandits and Dust Devils by a boy named Yury, he takes refuge in Yury′s home - an extensive network of tunnels known as Dunetown - and learns that Yury in turn needs Ros′s help. His family has been kidnapped by the sand bandits, a ruthless gang led by a psychopath obsessed with treasure and power.

Ros must learn to trust again, and to overcome those who cannot ever be trusted. Darker things lurk in the desert than Dust Devils and sand bandits. And, all the while, Adi′s voice is a constant reminder that time is running out ...
