I picked up this book expecting Artimis Fowel, Percy Jackson level and while it did have a lot of those younger elements it also odd how dark this book got at some points. I feel as if they had been humans instead of dragons there is no way they would have been able to publish this as anything but YA or adult. Example:

Having to see one of their guardians getting killed to protect them, Acid eating away at eye ball and body until death, Multiple killings by snapping necks, Fighting to the death against their will, torturing one who refused until he went insane and then one of the main kid characters is forced to kill him, Slaughtering a group of prisoners of war that were chained up for no reason without them being able to fight back, seeing multiple humans getting eaten alive or just slaughtered for entertainment, brainwashing of a child to become her killing machine, Elderly dragon taken to a high point and then dropped and letting him die a slow death in front of the child because he was her friend and taught her to read.

I'm sure I'm even missing some!
