I just finished reading "Attack of the Fiend" last night and I was not disappointed! My eleven-year-old son and I have been waiting for this one to come out, as we have read the entire "Last Apprentice" series and absolutely love every book. As usual, Joseph Delaney did a great job of scaring the pants off of us! From the first chapter, I was on the edge of my seat, terrified for Tom, the Spook's apprentice. Several times I had to put the book down and walk away to calm my nerves, but of course, couldn't stay away for long because I just had to see what would happen next. My husband even asked once, "What is the problem? I thought this was a kids' book?" and I had to explain that reading the Last Apprentice books is like watching a terrifying movie: your stomach is clenched with worry for these characters, but you're also dying to see what trouble they'll get into next. "Attack of the Fiend" had action and suspense from beginning to end and still, left us wondering when the next book will come out so that we can find out how Tom and the Spook plan to defeat the creatures of darkness. This is great book for anyone 10-100...as long as you're not afraid of the dark!
