The Fifth Tunnel

Being dumped in the Waste Pit is supposedly the worst punishment ever. But when Maeron Sharp swims beneath the Waste Pit's murky beginning, he finds a magnificent system of tunnels and caverns in which the water is breathable. Deeply tempted by each new mystery the Waste Pit has to offer, Maeron spends more and more time exploring underwater. And it might just be a quality of the waters, but the longer Maeron stays down, the harder it is even to want to leave.
