A very disappointing ending to a fantastic series.
The three dragon siblings join forces to save the world they helped to shape that is slowly decaying from corruption and abuse. And that's all. Sounds almost exciting, doesn't it? Well, don't get your hopes up...
Very little of anything happens in the book; it feels like a small bit of plot was stretched to fill a full-length novel. The little that does happen is not terribly exciting. The 'big reveal' of the big bad is not surprising, makes little sense, and comes so close to the end of the story that you are only given a chapter or two to accept the information before all is resolved in a very lackluster way. For a lot of build up to what could have been a promising and exciting climax, all problems are solved very easily and quickly.
The epilogue was slapped on last minute, I'll bet, because even that is very unsatisfying, with little more than a very brief summary of what became of the characters who survived the fight.
The book must not have spent very long with an editor because it is filled with conttinuity errors and typos.
I loved this book series. The first three books are some of my favorite books on my shelves and I reread them all the time. But the second half of the series slid downhill very quickly. Books four and five were at least a bit exciting and kept my attention; this last one felt like a chore to get through. I can't properly express my disappointment that such a wonderful series ended on such a dismal note.
