Extinct - Charles Wilson

Bought this book not long ago and read about 10 pages and just could not get into it. I lent it to a friend and she said it was really great.

Back Cover Blurb:
When the French government detonate a nuclear test on a remote atoll, something is woken deep in an ocean trench. The sharklike monster, thought to be extinct for 15 million years is hunted down and destroyed by a scientist. But its only a baby and his mother is lurking in the deep.
