Trixie & Me, by Peter Cawdron

Trixie & Me is a science fiction novella exploring alternatives to the Rare Earth Hypothesis in the search for extraterrestrial intelligence.
Trixie and Berry are trapped on an alien space ship. Berry can’t move, but he seems to understand what’s going on. Trixie is confused, she has no recollection of how they ended up in the dark depths of an alien war craft. She struggles to comprehend even the simplest of concepts, struggling to speak, but she is free of her chains, so she is Berry’s only hope. They must escape their captors and warn humanity about this sinister threat coming from the galactic core.
