My name is Callie Rose. My mum is a Cross - one of the so-called ruling elite. My dad was a Nought. My dad was a murderer. My dad was a terrorist. These facts are the only things that are mine and real. So I don't mind so much that I'm leaving it all behind. There's nothing here worth holding onto. Sixteen years have passed since Sephy Hadley first met Callum McGregor - and the hate that divided them turned to hope. But the world hasn't changed quickly enough for their daughter, Callie Rose. Growing up dual heritage in a world where bitter prejudice divides Noughts and Crosses has meant she's an outsider wherever she turns. Enter Jude McGregor. Jude teaches Callie about her real family history, and the more she learns the more he persuades her where her loyalties really lie. But soon Callie is caught in a trap she can't get out of - one which will have deadly consequences.

Years have passed since the love between Sephy - a Cross - and Callum - a Nought - destroyed their world and changed their families and society forever. Society appears to be very different now. For the first time ever, a Nought Prime Minister - Tobey Durbridge - is in power. Race and class don't divide people anymore. But things are never really that easy. Because Tobey's just been framed for murder, and the only way to free himself is to turn to his oldest friend - Callie-Rose. Their families divisions run deep, and when two young people are kidnapped, their lives and everything they've fought for are put in the firing line. And when you're playing a game as dangerous as this one, it won't be long before someone gets caught in the crossfire... Crossfire is the long-awaited new novel in legendary author Malorie Blackman's ground-breaking Noughts & Crosses series.

This is the system operator. Who is using this account? Please identify yourself... Vicky's life is completely normal. Maybe even a little boring. But all that changes when her dad is accused of stealing a million pounds from the bank where he works. Vicky knows for sure that her dad is innocent, and is determined to prove it. Luckily for him, she is a seasoned computer hacker. Using the skills he taught her, she's going to attempt to break the bank's files. Should be simple, right? But it's a race against time to find the cyber-thief, before they find her...

You're the new girl in school. You're just trying to fit in - and it's not working. Then someone accuses you of theft, and you think things can't get any worse. Until you get caught in a freak storm… The next thing you know, you're in the future. Being shot at for being out after curfew. You don't even recognise your hometown. And you're heading for a confrontation from your worst nightmare. What if you could change the past to save the future?

The first Nought Prime Minister, Toney Durbridge, is about to go on trial for the murder of notorious ganglord, Dan Jeavons. Tobey insists he is being framed. There were ten seats at Dan's dinner party the night he was killed and each guest had their own reasons for wishing him dead. Sephy Hadley was one of the guests that night. Haunted by the idea that she didn't do enough to stop the death of her first love, Callum McGregor, Sephy will not sit quietly and wait for accusations to fall on her now. She has her children to protect. It's time that the truth is uncovered. Time for the endgame. It's been 20 years since Malorie Blackman's groundbreaking series began with Noughts & Crosses, which charted the deeply forbidden romance between Sephy (a Cross) and Callum (a nought) - a love affair which had repercussions for their families for generations. Endgame, the breathtaking conclusion to the series, influenced by the unprecedented global events of recent years, is full of twists and turns. Are you ready for the Endgame?

'Stop it! You're all behaving like animals! Worse than animals - like blankers!' Sephy is a Cross: she lives a life of privilege and power. But she's lonely, and burns with injustice at the world she sees around her. Callum is a nought: he's considered to be less than nothing - a blanker, there to serve Crosses - but he dreams of a better life. They've been friends since they were children, and they both know that's as far as it can ever go. Noughts and Crosses are fated to be bitter enemies - love is out of the question. Then - in spite of a world that is fiercely against them - these star-crossed lovers choose each other. But this is love story that will lead both of them into terrible danger . . . and which will have shocking repercussions for generations to come.

No one could begin to guess at the depth of the hatred I held for Sephy Hadley. Everything began with her and my brother. And that's how it would end. Where there has been love, now there is hate. Two families have been shattered by the divided and violent society they live in. Sephy Hadley - a Cross, supposedly powerful and privileged - has bound herself forever to her nought lover Callum McGregor's family. But Jude McGregor blames Sephy for all the tragedies his family has suffered. And he is determined to force her to take sides, and destroy her life . . . just like she destroyed his. . .

Just this once. Just this once and no more, I promise. Please let me get away with it just this once . . . Tobey wants a better life - for him and for Callie Rose. He wants nothing to do with the violent gangs that rule the world he lives in. But when he's offered the chance to earn some extra money, how much could it hurt to just this once say 'yes'? Callie Rose knows all about the danger of saying 'yes'. She knows about terrible mistakes, and violence and revenge, and the fierce divide between Noughts and Crosses. And knowing so much about the past makes her afraid for her future. Because sometimes, one little bad decision can change everything . . .

Years after a violent war destroyed much of the world, Kaspar has grown up in a society based on peace and harmony. But beyond the city walls, a vicious band of rebels are plotting to tear this peace apart. It is up to the Guardians - an elite peacekeeping force - to protect the city, without ever resorting to the brutal methods of their enemy. When Kaspar joins the Guardians, he has a chance encounter with a rebel - a beautiful girl named Rhea. Haunted from that moment on by strange visions and memories - memories that could only belong to Rhea - he realises he hasn't been told the truth about what the rebels really want, and what he's really fighting for.
