'GRIDLOCK,' Part One 22,000 MILES UP, THERE IS (STILL) NO BACKUP. They call it Gridlocking-maglev-bike races across the Fuse's vast solar arrays. Fast, dangerous, and very illegal. When a gridlocker turns up dead, Klem and Ralph begin their own race to catch a killer! PLUS: Bonus backup strip 'TABLOID' starts this issue!
