It was a gripping read, to say the least. Really enjoyed how there are multiple story-lines and view points from several key characters. A bit surprised (and slightly let-down?) at the ending where things are left really open and is a set-up for a sequel without truly wrapping up the tale at hand. Now I am itching to read the next installment and feel a bit cheated by this dangling bait of a last chapter. The number of times where the adult zombies are described in gruesome details seems a bit on the excessive side — after the 10th vivid Enemy, I kind of had enough — so the subsequent drools, flabby skin, boils, rotten flesh, green ooze, etc. were simply skimmed over by this reader who was more interested in the next plot twist and how the children dealing with situations than visualizing the various lumbering decayed semi-corpses.Moments of the book made me think: “Whoa, Lord of the Flies crossed with The Animal Farm.” Especially when David (the self-proclaimed leader) keeps promising that he is not there to “rule” but to “sort things out” for others while schemes to suppress any opposition, with force and even with death of other kids.All in all — an entertaining read for those who are not disturbed by such violence and gore.
