I know that I, being as far behind as I was, read the entire Artemis Fowl series in a month and haven't been pursuing the saga over the 11 years I know most other readers have. But I was still very attached to this unlikely band of heroes and it was quite upsetting for the series to end. Still, as always, the book was wonderfully written, with Colfer's trademark wit and skill. His own genius did leave me questioning a few things (how can Opal kill her younger self?) and I truly did not expect Artemis to sacrifice himself like that, despite all his character development. All in all, a great book, a good end to the series, and a fantastic series overall. Will be getting my own copies to give to my kids in that far off future!
