(I know there could be some mistakes in this review. I’m trying to improve my English, thanks)
It is not my first reading written by three authors but I still do not figure exactly how this works. I think that -at least in this case- the best-known authors Larry Nivell and Jerry Pournelle decide about the big ideas and contribute with their names in the book's cover, while Steven Barnes writes most of the book. I say this because although Steven Barnes is an author with his own original books, he has also written a lot of franchise novelizations, for example some Star Wars novels.
The book has an interesting ecological premise but mainly it is a monsters novel. I confess it, I adoooore monster stories! In this case, the monster -or the alien animal- is a mix of Komodo dragon and aquatic velociraptor, which is quite interesting and well thought-out than it might seem. Of course, Heorot is from Beowulf’s poem so you can imagine how the colonists nickname the monster.
About the plot, this is the first interstellar colony for humanity, set in the fourth planet of Tau Ceti, ten light years from Earth. It has been an expensive voyage, both for the Earth resources and for the two hundred colonists that journeyed 100 years in suspended animation. Some of them awaked with apparently minor sequelae, their brain cells have been affected by the on hibernation, resulting in cognitive glitches. For example, the moving case of the Mary Ann character: she knows that before her long dream she was a genius in her scientific specialty and since her awakening she must strive to remember her knowledge. She continues being a viable person, she can work, she can love but she can not contribute with her knowledge to the colony. Fortunately, she will not pass her disability to her descendants...
The colonists choose a small island and begin to adapt to this idyllic planet. On the contrary of the highly recommended Sue Burke's Semiosis novel (you can read the review here), the colonists surprisingly do not care about the planet own ecology. For me this is the most nonsensical part of the novel, although of course in another case there would not be any story to write. Still, the authors could have thought it better. So the settlers sow the island with their own plants and they also have a lot of imported embryos from the Earth's fauna. Sue Burke's novel is hard science fiction and this one is mainly intended for entertainment. However, I must say that some other ecological premises of the novel -for example the part of the monster - are well thought out.
The Legacy of Heorot has two sequels that at this moment I do not know if I will read them one day. Another novel written by three authors that I remember right now is Hunter’s Run, a good science fiction story with an horrific alien too by George R. R. Martin, Gardner Dozois and Daniel Abraham. The latter, who later will be well known for the series The Expanse written under the pen name of James S.A. Corey, I understand that he was too the writer on behalf of the other two.
