I think Crystal is a great character, and she's most likely not going to meet our little trio of rebel future hero's for a while. But I think that if do the idea where we each write a chapter from our characters point of view, it could help the reader get some insight from an Ace's pov. Not only that, but possibly see how corrupt the government really is. It's just an idea, but if we make this a series. I think that Crystal could meet them in the second book, or right at the end of the first.
And if our trio is Nick, Eli and Liam, then the most important chapters, they would be Crystals chapters. Because not only would it change the focus off of the trio, but it would get the reader slightly aggravated by the fact that they know extra information that the trio doesn't know. And they would be counting on Crytal and the trio meeting. And our two extra characters, (who we need to name and make) they could add on to this in the story.
Kinda just went on a weird rant and I hope this makes sense to you all.
