These books are great, can't believe I just discovered them. And now that I have, I need more in the series! What happens next? What is everyone up to? I must know! Will there ever be a trustworthy male character? Will Bel and Rowan ever finally hook up? Will they save the world from Slado's mysterious scheming? Will they stop the genocide of the demons? Will they ever acknowledge that humans are far from the only sentient beings on this planet? Will they ever stop killing other species indiscriminately and destroying the ecosystem that exists around them? (Oh wait, I was talking about earth for a minute there.)

In summary, alert me as soon as anyone knows when book 5 is coming out.
