Demon's Bloodlust - New Guardian Generation, #1

I'm the chick stuck between three worlds and three men. Make the wrong choice and it could be the end of the world--literally. Althea and Nikolai are already meant for greatness. The children of infamous Promiscus Guardians, it is only natural that they would be expected to be nothing less than perfect when it came to their own careers as the protectors of Light and defeaters of Dark. But when a super villain and an old, unfortunate blast from the past come a-knockin', Al and Niko are forced to see their long-standing friendship in a totally different light.
And it might just put to test these childhood friends who don't know the first thing about love. The New Guardian Generation ventures into the already well-established world of the Promiscus Guardians. Old faces join new ones in this brand-new series. But the laughs, adventure, and romance are what you've come to expect of the Guardians.
