This was such an adorkable story! It's a really great look at geeks, fandoms, fan-shipping (relationships between favorite pairings of characters in fan-fiction, for those not familiar with the term), and conventions. 
 The main characters are well-defined. Brandon is battling with a crisis of faith and his homosexuality and spins a huge web of lies around himself where his video blog partner is concerned. Which becomes a problem because he's about to spend 6 weeks on the road with Abel (and Brandon's best friend, Becca), traveling around the country to various "CastieCons" (conventions for their favorite sci-fi TV show, Castaway Planet - Think Star Trek: The Next Generation and you won't be far off). 
 They're on a mission to find out whether or not their two favorite characters, Cadmus (the ship's captain) and Sim (an android), got down and dirty in a fade-to-black end-of-season cliffhanger scene. And they have a bet with a CadSim fan-shipper forum that says the men are strictly platonic. So, they're asking all the main cast members what they think happened at their Question & Answer sessions at the cons. 
 In the meantime, Abel is trying to get Brandon to get over a faked broken heart. He's pushy, but he means well. (If only he didn't have a boyfriend.) 
 They've also got some freaky stalkers following them around to the conventions, and they decide to mess with their stalkers once they figure out who they are and what they want. But at a cost they can't foresee. 
 It was a lot of fun to read, very sweet, and any sex is implied off-screen, not explicit. Definitely recommended.
