This is the last of the Coyote Trilogy. I reviewed Coyote here and Coyote Rising here.
This book is about thirty years in the future from the second book. The colony is becoming more stable and then a spaceship arrives from Earth. The European Alliance has developed starbridges and the spaceship will come apart to make one. The leaders of Coyote have to go back to Earth to deal with the new UN and other country groups and countries. Some of their treaties are not as wise as they could be and trouble ensues. A small band of rebels tries to stop the treaties and tension and danger mount.
This is a really good story, but the book needed a copyeditor. I checked and the earlier books were also edited by Ginjer Buchanan, but this one has minor continuity problems, misspellings (not typos), word misuse, and more. I kept being bounced out by this. Others may not have the problem.
Allen's anti-climax also includes a sneaky lead to the next book, which is not about Coyote. Spindrift, which I'll start tonight, is about the first EA shuttle that went through a starbridge, and was lost. At the end of this book, the survivors show up with an alien.
I do like the story, but if you're strongly conscious of editing problems, you may not like the book.
