Overall, this book is a strong 4 stars and a solid conclusion to the series. Though I do have some minor problems throughout this book, it can be overlooked.
Now, the overall plot is that this skilled elf named Muzien has basically taken over Haren's city of Valderen and it's up to him, Thren and their assassin equivalent of Dumbledore's Army (Including a Zachariah) to stop him. With that said, this was Haren's book; his culminating moment that has been building up for five books, previously, to shine and he does so to Muzien, as well as Thren. Not only that, but how the other characters, Alyssa, Zusa, Nathaniel, etc. are affected by this.
The last 50-100 pages of this book were the most important and action-packed of the entire book. The rest were just "the preparations for the final battle" as it is in many final books in a series. What I had a problem with, in the first part of the book was Alyssa and her decisions, especially when it came to Victor. I understand that in the previous books, men have not been so kind to her and seems to justify her actions for what she did o Victor because of it. I also don't hve a problem with Alyssa and Zusa's relationship; Go diversity, but I kinda liked Victor.
And let me just say, as a side note, that Epilogue had one of the biggest twist endings I have ever read. If you read it and want my opinion on what Zusa should do: I think she will. I really liked Haren and Zusa's friendship, almost shipped them after near the end of the 5th book (Wink Wink).
Anyway, this book had the reoccurring action and assassins and politics that it had throughout the series, which never got old for me. It had twists and turns, betrayals and surprising alliances. Again, not for comparing books to other existing franchises with their own original merits, but it's like Batman(slightly) meets Assassin's Creed(mostly). An overall enjoyable series, though nothing mind-blowing. Entertaining writing, though I would have to put A Dance of Shadows(Book 4) as probably my favorite out of them all.
