I'm going to do covers for the chapters. So this is for chapter 2, where we'll learn all about Zirra's past and find out why she's so bitter and how she is connected to Cynder.
i think i can answer that... when Zirra took over Cynder's body and used the crystal to change 'adult' Cynder into Zirra... it's just that, a change... sort of like a metamorphosis... quite possible reversible... not sure though... just a thought... (sorry to waste your time if it was already explained)
