It is early days yet...my release date for this book isn't until April but I guess there's no harm in starting to talk about it. *shrug*
There might be 2 or max 3 stories in the series, detailing (duh) the battle between good and evil, angels and demons, hummans and everyone else... - this isn't a terribly new idea, I know.
It also deals with Kai, our resident clueless and slightly curious angel who would like to try anything at least once - much to the annoyance of our resident hero, Alex.
It isn't so much the battle between good and evil, the fight to save the world which stands in the foreground here but it serves as a backdrop for how to fall in love and how to overcome despite the odds.
