How to Repair a Mechanical Heart

Eighteen-year-old Castaway Planet fans Brandon and Abel hate bad fan fiction—especially when it pairs their number-one TV crushes of all time, dashing space captain Cadmus and dapper android Sim. As co-runners of the Internet’s third most popular Castaway Planet vlog, they love to spar with the “Cadsim” fangirls who think Cadmus will melt Sim’s mechanical heart by the Season 5 finale. This summer, Brandon and Abel have a mission: hit the road in an RV to follow the traveling Castaway Planet convention, interview the actors and showrunner, and uncover proof that a legit Cadsim romance will NEVER, EVER HAPPEN.

A Brandon and Abel romance: also not happening. Brandon’s sick of his struggle to make “gay and Catholic” compute, so it’s safer to love a TV android. Plus Abel’s got a hot new boyfriend with a phoenix tattoo, and how can Brandon compete with that? But when mysterious messages about them start popping up in the fan community, they make a shocking discovery that slowly forces their real feelings to the surface. Before they get to the last Castaway Planet convention, Brandon’s going to find out the truth: can a mechanical heart be reprogrammed, or will his first shot at love be a full system failure?
