Orbit is to publish a novella by science fiction and fantasy author Brent Weeks in digital editions only, with the title set for simultaneous release in the US and UK.
Orbit publisher Tim Holman acquired world English language rights through Donald Maass at the Donald Maass Literary Agency to Perfect Shadow, which is set in the world of Weeks' Night Angel Trilogy.
Holman said: "The digital marketplace is an irresistible opportunity to publish shorter works of fiction. With over a million copies sold worldwide since its launch in 2008, Brent Weeks' Night Angel Trilogy has become one of the fastest selling fantasy series of all time.
"Publishing a new novella set in the same world, and doing so simultaneously around the world in e-book and audio editions, has been a really exciting publishing challenge".
The e-book edition and unabridged audio will be available from June 2011.
