Can't get enough of Andy Weir's The Martian? Dive a little deeper into his world, discover hidden treasures, and hang out with Mark Watney just a little longer with this sidekick.

Note: this is an independent companion to The Martian, meant to enhance your experience of the novel. If you have not yet bought Andy Weir's novel, make sure to purchase it before buying this unofficial Sidekick.

Mark Watney wasn't the mission commander of Ares 3, a month-long expedition to Mars. He was just the science geek, botany guru, and mechanical engineer: the lowest guy on the totem pole and the only one who didn't make it back to the ascent vehicle when the storm hit. Left for dead on the surface of a barren planet, Watney must plumb the depths of his considerable ingenuity and resourcefulness to find a way to survive - and to let the people on Earth know he's still alive.

Praised by The Wall Street Journal as "the purest example of real-science sci-fi for many years," The Martian has been on the New York Times best seller list for more than six months. It is Andy Weir's debut novel. With this sidekick, you'll:

• Learn what you might have missed on your first experience of Weir's novel
• Discover some of the book's secret gems and underlying themes
• Explore possible alternate endings and imagine ideas for a prequel
• Spend some more time with the characters you've come to know and love, delving deep into their psyches and hidden motives
