After two trilogy chapters, the sequel even better than the first, this final book is sadly disappointing. With the real threat eliminated by the end of the second book, this entry feels more like a 600 page epilogue. The first third is a flashback to the human life of the main antagonist before the fall of humankind explored in the first installment. A slog to get through, as I found it impossible to care. The rest is equally pointless.
