Ernest Cline's new book follows a high school kid, seriously obsessed with 80's pop culture due to the influence of a missing father figure, who uses his video game skills and trivia knowledge to try to save the day and win the girl.Unfortunately this description applies equally to Cline's first book, the wonderfully received "Ready Player One" from 2011, and his second novel "Armada," released last week, and if you've already read "Ready Player One" you'll feel it looming over "Armada" like a better-looking older brother the whole time you're reading.Teenager Zack Lightman is one of the top ten players in the world in the space-war video game "Armada," something that helps keep his mind off the fact that his father died in an embarrassing industrial accident years ago, leaving Zack and his mom alone.Suddenly one of the enemy Subrukai ships from the game appears in real life and Zack's world changes as he is abruptly conscripted in front of his whole high school into becoming an elite fighter pilot for the Earth Defense Alliance based solely on his gaming abilities.
