QQC: 3rd book of Maximum Ride

Right now, I'm reading Maximum Ride: Saving the World and Other Extreme Sports. It's the 3rd book of the series and I think I blogged about the first 2 a little while back. Here's the quote I picked out for this week: "Oh,no. The Voice was not connected to the chip. It was still inside my head. Which made today's total: 1) Useless left hand 2) Fang believing some mushy emotion I didn't even mean 3) Voice still with us" So, some of the questions I have are: If the voice isn't coming from the chip, where is it coming from? What does the chip do? Was it a tracker for the Whitecoats to see where she is? I think it was pretty stupid for her to get that operation for a couple reasons. One of them is she doesn't know what the chip does and she wants it out. Another would be losing her left hand. She didn't really lose it. It's still there, but she can't move it which makes it completely useless and she still needs to "save the world." I can tell while reading the book that she kind-of regrets having that operation done on her, but she wanted it and everything went downhill for her right after. The book is getting really interesting though. Well, that's pretty much it.:)
