Erak's Ransom is the seventh thrilling book in John Flanagan's Ranger's Apprentice series - over eight million sold worldwide.

In the wake of Araluen's uneasy truce with the raiding Skandians comes word that the Skandian leader has been captured by a dangerous desert tribe. The Rangers - and Will - are sent to free him.

But the desert is like nothing these warriors have seen before. Strangers in a strange land, they are brutalized by sandstorms, beaten by the unrelenting heat, tricked by one tribe that plays by its own rules, and surprisingly befriended by another. Like a desert mirage, nothing is as it seems. Yet one thing is constant: the bravery of the Rangers.

Perfect for fans of J.R.R. Tolkien's Lord of the Rings, T.H. White's The Sword in the Stone, Christopher Paolini's Eragon series and Rick Riordan's Percy Jackson series.

Rick Riordan's Norse hero faces his greatest challenge yet in the final instalment of the series.

Loki the trickster god is free from his chains. Now he's readying Naglfar, the Ship of the Dead, armed with a host of giants and zombies, to sail against the Norse gods and begin the final battle of Ragnarok. It's up to Magnus Chase and his friends to stop Loki's plans, but to do so they will have to sail across the oceans of Midgard, Jotunheim and Niflheim in a desperate race to reach Naglfar before it's ready to sail on Midsummer's Day.

Along the way, they will face angry sea gods, hostile giants, and an evil fire-breathing dragon who happens to be a former acquaintance. But Magnus's biggest challenge will be facing his own inner demons. To defeat Loki, Magnus will need to use words, not force. This will require finding a magical elixir so deadly that it will either make Magnus Chase powerful enough to out-talk the silver-tongued Loki, or destroy Magnus utterly.

Rick Riordan, dubbed 'storyteller of the gods' by Publishers Weekly, is the author of five New York Times number-one bestselling book series with millions of copies sold throughout the world: Percy Jackson, the Heroes of Olympus and the Trials of Apollo, based on Greek and Roman mythology; the Kane Chronicles, based on Egyptian mythology; and Magnus Chase, based on Norse mythology. Percy Jackson and the Lightning Thief, Rick's first novel featuring the heroic young demigod, won the Red House Children's Book Award and is now a blockbuster film franchise starring Logan Lerman.

The final, thrilling instalment in this extraordinary series from bestselling authors Holly Black and Cassandra Clare.

A generation ago, powerful mage Constantine Madden came close to achieving what no magician had ever achieved: the ability to bring back the dead. He didn't succeed . . . but he did find a way to keep himself alive, inside a young child named Callum Hunt.

Facing up to what he is, Callum has battled chaos and evil across four years of magical training at the Magisterium, eventually defeating the armies of chaos in an epic battle.

It came at a cost.

Now, triumphant and heartbroken, Callum Hunt has just about had enough, and is ready to complete his training. But the evil Callum faced has not given up just yet . . .

Callum Hunt's life has fallen apart.

His friend is gone. The spy has escaped. His secret is out.

He is facing an existence behind bars, banished from the rest of the magical community for what he is - for what he might become.

But a shocking revelation has promised freedom - at a cost. Will he stay strong, and faithful to his friends and teachers? Or take the risk, and destroy everything he's ever loved?

This fourth year at the Magisterium will be unlike anything else that has gone before . . .

'I can't wait to read more of this series!' - Rick Riordan

Magic can save you
Magic can kill you

It should be a time of celebration. The Enemy of Death is dead; a severed head proof of his downfall. The magical world has no reason to believe otherwise, and Callum, Tamara and Aaron are celebrated as heroes.

But at a party held in their honour, things go horribly, brutally wrong. A fellow student is callously murdered, and it seems Call's worst fears are confirmed: there is a spy in the Magisterium.

No one is safe.

Now, using the powerful magic they've been taught, the trio must risk their lives to track down the killer. But magic is dangerous - in the wrong hands it could bring terrible destruction. And reveal the deadliest secret of all . . .
