The Battle of the Labyrinth by Rick Riordan, 361 pages
Percy Jackson and his demigod pals are preparing for the upcoming war between the gods of Olympus and the Titan Kronos, when they're sent on a quest through the mythical Labyrinth in search of the string of Ariadne and the lair of Dedalus. Oh, and the Great God Pan, who has been missing for almost 2,000 years. As with the other books in this series, many battles with mythological baddies ensue. My family listened to this one in a car trip to Mammoth Cave National Park, and we found the underground labyrinth setting particularly appropriate for our destination. Generally speaking, Jesse Bernstein did a good job narrating, though the horse-y voice he used for the pegasus Blackjack and the stereotyped Asian voice he did for demigod Ethan Nakamura were both cringe-inducing, though for very different reasons. Otherwise, though, this was a good one!
