Ooh please write more!
One minor thing:
When Kali is running through the tunnels, Ryger's father says “Ryger...It is your job to protect her. We are needed here, but we’re confident in your abilities. We’re trusting you. Don’t let anything happen to her.” I don't think he'd talk that long because Ryger's gotta catch up to Kali! Plus I think it would have more of an impact on the reader if it was condensed.
Excellent so far, though. Keep writing!

I like the way you set the mood for the prologue. I don't have time to finish the first chapter but I like the way you described her surroundings. This will be an interesting story.
