The planet Botany was settled by a mixed group of humans and aliens, slaves of the alien Catteni and their alien masters, the Eosi. But one Catteni was dropped on Botany with the slaves: Zainal, who helped them win their independence. Now Botany must establish trade with other planets in order to survive. But the other worlds have been ravaged by the Catteni, and once-proud Earth has been reduced to primitive poverty, its technology stolen by corrupt Barevi merchants. To save Botany, Zainal and Kris Bjornsen, his human lover, must find a way to help all the worlds.
While the preface of Freedom's Ransom crisply summarizes the preceding books, this series has so many characters, races, and planets that newcomers should start with the first book, Freedom's Landing. Sophisticated SF readers aren't likely to enjoy the series, but it should hook young adults; if you're looking to broaden a child's reading beyond Harry Potter, try Anne McCaffrey's Freedom series and Dragonriders of Pern series. --Cynthia Ward
