Altruistic space pirates, nuclear-powered djinn, a time-traveling kangeroo—and more ... Three complete novels of humorous adventure, one of them a Hugo Award finalist, plus a trio of witty short stories with the distinctive Leinster touch.

The Pirates of Zan—When a young man is accused and jailed unjustly, he is given a secret offer—in return for help in escaping, he must shake up the galactic establishment, which is getting dangerously set in its ways. He succeeds beyond anyone's wildest expectations, seemingly becoming a space pirate, but being in reality, the deadliest do-gooder in the galaxy.

Gateway to Elsewhere—Suppose that somewhere the world of the Arabian Nights is real, including very powerful and dangerous djinns, who are nothing like Aladdin's big blue pal. A man from our world wouldn't have a chance against them ... or would he?

The Duplicators—A planet where everyone has a machine which can duplicate anything would be the wealthiest world in the galaxy, right Wrong. And unless the hapless voyager who's trapped on the planet can find a solution to its problem, his voyaging will be over—permanently. Plus three short stories, including "A Logic Named Joe," an uncannily prophetic story of home computers and the internet—written in 1946!
