Books with author Sean Williams and Garth Nix

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?

Trouble is looming over the quiet coastal town of Portland. Evil is stirring. Strange things are starting to happen and Jack and Jaide are right in the middle of it. Their destiny is about to unfold. When their home mysteriously explodes around their ears, twins Jack and Jaide are sent to stay with a grandmother they have never met, in a town they have never heard of. Portland might seem boring and quiet, but it soon becomes apparent that Grandma X is more than a little eccentric, and there are very strange happenings in the town. Talking cats, swarms of cockroaches, a miniature tornado trashing their room – the twins are about to find out what it means to be a troubletwister!

Since moving to the town of Portland, many bizarre things have happened to Jaide and Jack Shield. The twins have discovered their own magical powers — and have seen how they can go horribly wrong. They have met cats who talk and humans who keep silent about deep, dark secrets. And they have begun their fight against a deadly force known as The Evil. Still, Jaide and Jack have yet to meet the strangest resident of Portland. It’s a creature that comes out only at night, a beast that defies human description. Jaide and Jack have never seen it...but they’re about to. And when they do, destruction and disaster won’t be too far away. Magic. Monsters. Terror. TROUBLETWISTERS.

Trouble is looming over the quiet coastal town of Portland. A door has been opened to the Evil Dimension, and twins Jack and Jaide are about to face their greatest challenge ever ... Jack and Jaide Shield finally learn what it means to be a warden in training as they pit their wits and gifts against mysterious fellow troubletwister Stefano Battaglio. But the competition soon gets serious when a way is opened to the dangerous realm of the Evil. Grandma X discovers her twin sister, Lottie, is stranded there - but she's forbidden from travelling through the vortex to look for her. That doesn't stop Jaide and Jack from trying, and the rescue becomes urgent when the twins find out about a plan that will trap Lottie on the other side forever. Can the twins find Lottie, defeat the Evil and get everyone safely home to Portland - before it's too late?

When eccentric Young Master Rourke dies in suspicious circumstances, troubletwisters Jack and Jaide are sent on a mission by their father to retrieve a lost Golden Card from somewhere within the vast Rourke estate. But secret agents for The Evil are also in pursuit of the card, and the troubletwister twins know that whoever finds it first will gain access to a Gift more powerful or terrible than any other. Together they negotiate secret passages, talking parrots and animated suits of armour, while trying to control their own fledgling Gifts. It rapidly becomes impossible to know who to trust and who might be an agent – even among those closest to them.

An action-packed fantasy adventure series from the authors behind Sabriel, The Keys to the Kingdom and The Fixers. 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. In this gripping new series of fantasy stories, international best-sellers Garth Nix and Sean Williams combine to create a world that will have boys and girls aged 10+ absolutely gripped. Ideally suited to fans of Percy Jackson and Harry Potter. Can twin siblings Jack and Jaide protect the earth from marauding Evil? Find out in Troubletwisters 3: The Mystery.
