The Swarm: A Novel - by Frank Shatzing.

"Whales begin sinking ships. Toxic, eyeless crabs poison Long Island's water supply. The North Sea shelf collapses, killing thousands in Europe. Around the world, countries are beginning to feel the effects of the ocean's revenge as the seas and their inhabitants begin a violent revolution against mankind. At stake is the survival of the Earth's fragile ecology—and ultimately, the survival of the human race itself.

The apocalyptic catastrophes of The Day After Tomorrow meet the watery menace of The Abyss in this gripping, scientifically realistic, and utterly imaginative thriller." - Amazon

This is one of my favorite modern sci-fi novels. Accustomed to reading mainly non-fiction, this book had me hooked by page 3...and with 912 (yes, 912!) pages of remarkably accurate science --at least in premise, albeit taking several surprising turns towards more classical sci-fi genre-- to infuse this gripping story, Shatzing does a wonderful job of creating engaging and though-provoking story lines and characters. I loved the reflective and social critique behind it. Certainly worth a read, and likely a great gift for any sci-fi fans out there, who like me are fans of sci-fi classics a la Jules Verne!
