The extraordinary new novel from one of the most exciting and original new talents in world SF.
Tighe lives on the wall. It towers above his village and falls away below it. It is vast and unforgiving and it is everything he knows. Life is hard on the wall, little more than a clinging on for dear life.
And then one day Tighe falls off the wall. And falls, and falls, and falls . . .
Lavishly praised everywhere from Asimov's magazine to Interzone, ON is proof positive that Adam Roberts is a new author whose potential for greatness is rapidly being realised.
ON is at once a vertiginous concept novel, a coming of age saga, a picaresque journey across a changed world and an epic adventure in the very best traditions of SF.
Adam Roberts is the author of 14 SF novels, most recently Jack Glass (which won the UK BSFA and the US John Campbell awards for best SF novel, 2013), as well as a number of critical works about science fiction, including Science Fiction (Routledge, 2000) and The Palgrave History of Science Fiction (Palgrave 2006). He regularly reviews the genre for The Guardian and is also a Professor of 19th-century Literature at Royal Holloway, University of London; where he also teaches Creative Writing to undergraduates, specialising in 3rd-year final projects in SF and Fantasy.
