Bücher der Reihe The Demon Gatekeeper

The battle's won, the demons sent back to hell, but the war isn't over, the werewolves are out for revenge! Lewis and Charlie are the last two remaining blood royals, the most powerful magical creatures in existence. They've had a lot of growing up to do, and fast. They've learnt how to control their magic and even saved the earth from disaster, but the werewolves are still on the loose and it's only a matter of time before the demons find a way out of the pit. In order to stop them, Lewis and Charlie, helped by their lycan friends (and a few handy humans), need to find the ultimate magical weapon, the demon killer, and put an end to the monsters, before they can take over the world. Shoulders of Giants, book two of The Demon Gatekeeper trilogy, is a thrilling ride through a world full of magical creatures, with angry werewolves, vengeful angels and even a two-headed dog.
