Other Side of Night: Bastian and Riley by S.L. Armstrong and K. Piet (Storm Moon Press)
"Vampires walk among us. For centuries, they have adapted, learning to pass undetected in our world. They no longer fear the day, only the sting of direct sunlight. They are students, bankers, lawyers, and even actors. But when the sun goes down, they are all united by their eternal thirst. We do not see them from our safe and comfortable side of the night. But sometimes, one of us is drawn away from the light and we cross into their world. Into the other side of night."
