Trajectory is the prequel novel to Carissa Andrew's Pendomus Chronicles, and it gives us a little peek into some character origins - or at least I think it does. I feel like you'd need to read the part of the series first to truly understand the importance of what happens in Trajectory. But if you haven't read them yet, then prepare to be intrigued by two completely different worlds and the people within them.

I really liked the way the Helix was described. The glimpse of a potential utopian society, but we all know where that leads. The Lateral was also interesting, but not so much because of the society, but the characters. I felt like I got to know them better than the Helix characters.

Definitely worth the read if you have read or plan on reading the Pendomus Chronicles.
