[Note: I received this book for free from the publisher in exchange for an honest review. This in no way affected my opinion of the book, or the content of my review.]
*Contains spoilers*
Very classic fantasy book, with the usual setting populated by orcs, dwarves, elves, humans and...vampires. This, and the different planes of existence setting, is the real twist of the novel, which for the rest develops in a fairly straight way. I would not be surprised if the authors are campaign builders for the Planescape Dungeon and Dragons setting.
Nevertheless, I enjoyed this book very much as it was some time since I read a well built world model and good development of the main characters. And from time to time you just need this!
Some minor typos in the books, which could be due to maybe having received a draft copy for review.
The book leaves you wanting for more, which will probably happen as we would like to know how the war with Taza evolves once the staff of Adaman is fully retrieved.

Thank you.
Enjoyed it.
Will purchase copies for family and friends.
