Amy Pill is a genius and a slacker who’d rather surf than grind out her day job in 2439, building anti-gravity units for deep-space vehicles. But when her shoddy factory begins to implode around her and her sister Victoria, will her gritty genius be enough to save her? Also contains the sequel Gravity Matters: Blackline, featuring Victoria and Amy's perilous escape from blackhole energy space zombos! Written by Jeff Rider with art by Sean Dillon. The print edition also features the special one-shot Gravity Matters: Playtime with art by Betsy Petershmidt.
