Ruby Forest. Duology

The lands of the Circle are under a terrible affliction — people are disappearing without a trace in a mysterious red fog. It advances ever closer to the royal walls, but the council anxiously remains silent: no one knows what to do. The precious princess Ruby and the dragon Solaris, bound to her by a curse, set off on a dangerous journey to deal with the looming threat. They must cross an entire continent, reach the dragon island, and figure out what really happened on the Night of Death — the night of the tragedy that began the feud between dragons and humans.
