Hominids:

Book #1 of The Neanderthal Parallax
    By Robert J. Sawyer.

Format.
    Audiobook read by Jonathan Davis.

The Book in One Sentence.
    A Neanderthal named Ponter Boddit accidentally travels from his own universe into ours, and in so doing exposes both unique cultures to one another.

The Good.
    I enjoyed a lot of the science and philosophy discussions.  Boddit's people have a view on how the universe works that is far different from our own.

The Bad.
     Some of the relationship dynamics seemed a bit forced.

Who would I recommend it to?
    People interested in parallel worlds, alternate history and/or Neanderthals.

A Quote from the Book.
    "Pennies from heaven."

Verdict.
    I love how this book ended.  Definitely going to read the rest of the series.
