I really enjoyed Philippa Ballantine's book Geist, the first Book of the Order which has an amazing cover. I'm happy to show you the cover for the sequel, Spectyr, that has been released and I have to say it's just as beautiful as the first! It will be released June 2011.
In other news, Ballantine has reported that on top of Spectyr, there will be two more books set in the Geist world! The title of the third book is Wrayth, and the fourth has yet to be named.
