Paragaea is a modern take on the old "other world" genre of science fiction (well, science fantasy), in which the protagonist is somehow transported to an Earth-like world that is definitely not Earth. The most famous example would probably be Burrough's A Princess of Mars (and its sequels) or L. Frank Baum's Wizard of Oz. In this case, Soviet cosmonaut Akilina (aka Leena) Chirikov pops through a wormhole in the midst of her Vostok 7 orbit and ends up crash landing onto a strange new world called Paragaea. Leena is immediately set upon by a strange race that looks like a hybrid of cats and people and is then rescued by a jaguar-man named Balam and his human friend, Hieronymus Bonaventure, a fellow Earth-native who got pulled through to Paragaea during the Napoleonic Wars during which he was serving in the Royal Navy. Accompanied by these two and various others that they meet along their road, Leena sets out to find a way to return to Earth and complete her mission. Paragaea does several things well. Leena is a very convincing 1960's Soviet woman, her attitudes and worldview feel right for her era and origins and makes her confrontation with a world that doesn't meet her beliefs a fascinating process. Likewise, I loved Roberson's idea for Paragaea, a world populated by the detritus of wormholes from Earth that drop things in from all time periods: past, present, and far-future, and mix it all up in one confusing and fascinating melange, the world development is excellently done, though the book does suffer from a fantasy convention I think of as "world-shrink" in which an author doesn't seem to understand the sheer size of the land-masses involved. Here, Roberson creates a Godwana-size supercontinent and proceeds to send his characters to every corner of the continent in a few months with only the most basic means of pre-industrial transportation (apart from a short jaunt in an airship). Another issue I had was that the other major protagonist Hieronymus doesn't feel anywhere near as authentic to his era as Leena does. One could put this down to the fact that he's been on Paragaea for longer, but frankly I just couldn't buy the idea that Hieronymus was an early 19th century British sailor with middle class upbringing; he's a likeable and amusing character (indeed, Roberson's characters are all quite likeable), but he's not authentic. Similarly disappointing is the fact that the main story is pretty thin (and is held up in large part by the world development), mostly involving Leena's quest to get back to Earth, other things intrude and through them we get a glimpse of the history of Paragaea, but they are tangential and very little is resolved. The fact is that Paragaea's selling point is its world development, and if you like "other world" adventures (and I, for one, do find them fascinating) then this book is a worthwhile read.
