Piranha (The Good Version) - Thoughts?

I read the novel recently. John Sayles wrote it too.

Breezy read.

Neither did I until a few months ago.

"The last wet-suited tourist in line suddenly felt one of his flippers loosening, and in an economic movement he turned in the water and brought his foot up to adjust it, a stream of bubbles rushing from his air-tank. Tightening the flipper, he glanced back through his mask the way he had come—and saw something. Peering harder into the murky water, his eyes suddenly widened and bulged out of their sockets as he saw what it was.
Fish. A whole school of them, moving as though with one mind through the dark water, straight towards him. But they weren’t ordinary fish. Their open mouths were lined with teeth—teeth that looked like twin rows of murderous needles—
The sight of the piranha held him rigid for a few seconds—and that was too long. Before he knew what was happening, and before he could do anything to warn his friends, the shoal was sweeping over him. Swarming, they covered him—and as he opened his mouth to scream, losing his air tube and gulping water, the lake around him began to churn wildly."

"Unconcernedly, the fisherman finished his baiting, and stood up to make his cast. The line flicked through the air in a glitter of silver and splashed into a rolling wave. It sank into the green water, drifting down, down through the turbulence to the cool, still depths below, where it hung tantalisingly, a lure that no fish could resist, hopefully.
And it wasn’t long before something did come investigating. Or rather, several things. Ten or fifteen or them, swimming in from the darkness deeper out in the sea, nosing around the hook, looking, as they were forever looking, for something to satisfy their insatiable appetite. Snapping, their needle-sharp teeth demolished the bait in seconds, breaking the line and sending the hook spiralling down to the sand at the bottom. Then realising that there was nothing more for them here—that they must look elsewhere for better prey—the survivors of the piranha shoal swam on along the quiet, peaceful coastline."
