BBC One has commissioned a TV adaptation of Noughts and Crosses, the groundbreaking young adult book by Malorie Blackman OBE.
It'll be based on the first award-winning novel in the series - a tale set in a fictional, alternative-history dystopia where prejudice and segregation run deep, following two teenage characters who are breaking all the rules.
Protagonist Sephy Hadley is a 'Cross' - a member of the black ruling class - while Callum McGregor is a 'Nought', a member of the white underclass. Strict race laws mean that the two of them can never be anything except friends… but they've fallen in love.
The novel was originally released in 2001, and, along with the other books in the series, saw huge critical success. Award wins included the Red House Children's Book Award and the Fantastic Fiction Award, and the series' success helped Blackman secure her position as Children's Laurate from 2013-15.
Noughts and Crosses has been adapted for the stage and radio in the past, but this is its first time on telly.
Malorie Blackman said: "I am beyond thrilled that Noughts and Crosses will be dramatised by the BBC - it couldn't have found a better home. Callum and Sephy seem to have meant a lot to readers over the years and I'm excited at the prospect of watching them on my TV!"
The adaptation will be written by Levi David Addai (Youngers, My Murder) with Matthew Graham (Life on Mars), and produced by Mammoth Screen - the company behind Poldark.
There's no word just yet on casting, but it looks set to hit our screens some time next year.
