Since people have asked about the Lightworld/Darkworld novels:
Queene of Light will be out in October.
Followed by Child of Darkness in November.
And the whole thing concludes in Goddess of Light in December.
You can buy all three for someone for Christmas.
And yes, if you want to post the cover in your blog or whatever, go to town. SPREAD THE WORD, MY GORGEOUS FLYING MONKEYS!
