The story should have been shorter. I didn't like Cara. Author wanted to show her as a cute perky genius but it didn't work for me. She annoyed me. I understand why Jarak was so upset. You can't have a person on a spaceship, who wants to take everything apart to see how it works. I was actually surprised they reached Valdier in one piece.
The main characters didn't communicate. They didn't discuss their problems. Something happened and Cara's reaction was to run away and Trelon had to chase after her again. They had sex and it seemed to solve all their problems.
I'm still interested in the world and this race's existence. I'll probably read the third book. Hopefully Trisha is a lot more pleasant and saner than Cara.
