Don't be evil. That's Google's official motto. But what's really going on behind that simple little search box? Wired's Steven Levy guides us through a history of the rise of the internet, the development of complicated search algorithms, and, in many ways, a who's who of Silicon Valley — all beautifully narrated by L.J. Ganser.

What started as two geeks obsessed with improving internet search engines rapidly ballooned into a company eager to gobble up other useful startups (Keyhole Inc., YouTube, Picassa) as well as larger, more obviously valuable companies (most notably the marketing goliath, DoubleClick). Google's strategy has also been a game-changer in regards to the way we use data and cloud computing. Thanks to its highly lucrative AdWords and AdSense programs, the company exploded the way people think about the internet and the way people think about making money on the internet.

In the Plex gives listeners a real idea of what it's like to exist within the company's quirky culture. And Ganser knows when to keep it serious, but that doesn't stop him from adding just the right amount of snark to the “like” and “um”-ridden quotations from various engineer types. This edition also includes a fascinating interview between the author and early hire Marissa Mayer, the youngest woman to ever make Fortune's "50 Most Powerful Women in Business" list.

Levy dedicates a large section of the book to Google's controversial actions in China, the ultimate test of the company's “don't be evil” philosophy. Here, In the Plex takes an unexpected turn from company profile to a technology coming-of-age story for notorious “founder kids” Larry Page and Sergey Brin. How does “don't be evil” play out in a real world that is sometimes, well, evil? Results are mixed.

In addition to China, Levy touches on some of Google's failures, flubs, and flops, like the company's book scanning project and its development of Google Wave and Google Buzz. However, he seems to miss the point when he makes excuses for their inability to compete in the social space. It seems particularly obvious why a corporation completely run by data-obsessed engineers would have trouble making inroads in the world of social media, which is by nature more organic and subtle.

From the early days as a gonzo-style startup to the massive corporate giant that has quickly integrated itself into almost everything we do, this is an essential history of Google. —Gina Pensiero
