Larry Niven and Edward M. Lerner are pleased to announce the mass-market re-release of Betrayer of Worlds, the latest installment of their collaboration in Known Space.

Trapped in the Wunderland civil war, all Louis Wu wants is a way home. What Nessus, the insane Puppeteer scout, offers Louis instead is a way out — through unknowable danger. Because someone must prevent catastrophe for the Fleet of Worlds.

And in this crisis, the winner takes . . . worlds.

“Rescues, captures, kidnappings, reluctant temporary alliances, backdoor negotiations, propaganda campaigns, bluffs and double-bluffs, alien and cross-species politics, and, of course, betrayals. Lots of betrayals … One hopes that Niven and Lerner come up with some additional twists and turns.”

— Locus

Betrayer of Worlds is Lerner and Niven’s fourth novel together. The opening book in their series, Fleet of Worlds, was the “Sci Fi Essential” novel for September, 2007. Fleet of Worlds went on to be named a finalist for the 2008 Prometheus Award. (Books two and three of the series are Juggler of Worlds and Destroyer of Worlds.)
