Dragon Home (Supernatural Consultant #5.2)

With Rios happily mated and planning an entire future, Aqua can't help but feel left out. The brother that had always been his chief playmate and best friend is going to leave him behind, which isn't at all acceptable. The obvious answer is to leave first, so Aqua packs a bag to go on an adventure. But this adventure isn't anything like his last one and the chances of him returning home alive dwindle every moment.
