Avalon: The Warlock Diaries: v. 3 by Rachel Roberts
The race to find Avalon is on! This time it's up to the warrior mage, Adriane, to lead the charge across the magic web and rescue the animals of Ravenswood before they are turned into evil warlock minions. The mages will need all the help they can get to stop the warlocks, including the mistwolf pack and a group of ferocious dragons. But even that may not be enough to save their friends and protect the home of all magic: Avalon.
