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?
