The novel “Coyote Frontier” by Allen Steele was published for the first time in 2005. It’s the third novel in the Coyote series and follows “Coyote Rising”.
When a spaceship from the European Alliance reaches Coyote, its inhabitants are preparing for the worst. Twenty years have passed since the rebellion but Carlos Montero hasn’t forgotten that difficult period so he’s ready for anything even if Captain Anastasia Tereshkova has communicated that her intentions are peaceful and actually intends to open a new way of communication through a portal.
For Coyote’s inhabitants the situation is completely new. Computers and other equipment available are old and slowly failing, getting new supplies would improve everyone’s life. The priority, however, is to maintain their independence but in establishing business relationships with the Earth there’s the risk of repeating the mistakes made on the mother planet.
