Gearz #4 [EPUB ebook] 

Homecoming wasn’t supposed to be like this: The teachers have become chemically boosted monsters. The football players have become something worse. And the government assassins and their killer robot only care about destroying Karen Chugg’s three robot bodyguards. It’s up to Marcia, Jan and Cindy – the high school’s newest robotic superstars — to save homecoming, and themselves, in the finale to the GEARZ mini-series.
