Since I started my new job, I now have a 35-40 minute commute to work so I started listening to audiobooks again. I found a free audiobook called Singularity by Bill DeSmedt at podiobooks.com. From the site:

What if the cataclysmic Tunguska explosion of 1908 was caused, not by a meteor or a comet, but by a microscopic black hole?

What if that fantastic object – smaller than an atom, older than the stars, heavier than a mountain – is still down there, orbiting deep inside the earth, slowly consuming the planet?

What if only a rookie government agent and an uncannily-insightful consultant stand between a renegade Russian billionaire and his plans to use the black hole to change history – or end it?

What if it’s all true?

I thoroughly enjoyed Singularity – in fact, there were times I didn’t want to leave the car because I was so involved in the story. The author does a great job narrating and really keeps you involved. It does gets a bit technical at times with things like quantum theory, the time-space continuum, etc. but it was action-packed and quite entertaining.

If you’re looking for an action-thriller with a scientific bent to it, you can’t go wrong with Singularity.
