But there was a spell in effect to keep him alive. It was obviously something the dragon had developed over many years for the comfort of its human visitors. It was comprehensive. It was user-friendly. It had the feel of magic finely milled by long centuries of use and cast by a past-master with wings and a tail. Quentin wasn’t going to die. Or at least not by accident.

In fact he felt warm, for the first time in what seemed like hours, and he could see clearly, if dimly, which he shouldn’t have been able to do. He was breathing the water. It wasn’t quite like breathing air—it had more heft to it, more push and shove was required to get it in and out of his chest—but it got the job done. Oxygen continued to reach his brain. He heaved it in and out gratefully, in big gulps. He felt relaxed. Somebody was taking care of him. He was flying first-class.

Quentin had always had reservations about dragons, the real ones anyway, the ones that actually existed. He’d been raised on the tradition of high-flying, gold-hoarding, fire-breathing dragons. Beowulf dragons, Tolkien dragons, Dungeons & Dragons dragons. The news that real dragons lived in rivers, and didn’t go thundering around the countryside setting trees on fire, had come as a disappointment to him. River dragons sounded colder and slimier and more newtlike than what he’d been hoping for.

So he was happy to see that the dragon that had hold of his ankle with its short but powerful right forelimb, drawing him down and placing him gently on the canal floor, like a puppy to whom it was saying “stay,” was thoroughly, almost quintessentially draconian. It looked sinister and coldly calculating and like it could eat him without noticing, but it was canonical. Its massive saurian head was the size of a compact car. Its eyes flashed silver when you caught them at the right angle. Its scales were a delicate watery green. Having settled him on the soft sand, the dragon of the Grand Canal released him and crouched down in a catlike pose, resting its head on the tip of its tail. Its vast body humped up in the dimness behind it.

Quentin sneezed. His sinuses had flooded with filthy water when the dragon yanked him down, but the water around him now was clean. He was enclosed, with the dragon, in a quiet green-black dome of water. The canal bed, which should have been a swamp of trash and scrap metal and sewage, was smooth. The dragon kept its patch of sand well tended.

Quentin sat cross-legged. It was just the two of them; the dragon hadn’t taken Poppy, apparently. Quentin was having a little trouble not floating away, but he found something round and heavy next to him—an old cannonball, maybe—and settled it in his lap to hold him down.
