Part survival handbook, part page-turner, Improbable Botany is a fond companion piece to many of Wayward’s past collaborations and features newly commissioned short stories by eleven multi-award winning science fiction authors: Ken MacLeod, Cherith Baldry, Eric Brown, Rachel Armstrong, Simon Morden, Adam Roberts, James Kennedy, Stephen Palmer, Justina Robson, Tricia Sullivan and Lisa Tuttle.

The book has been edited by Gary Dalkin, a former judge of the Arthur C. Clarke Award and former editor of Vector: The Critical Journal of the British Science Fiction Association.
