Hey WC,Your writing is refined. I had no problem with the mechanics of the 13.
Unfortunately, I have no idea what's going on. Also, the clash of locations makes me go huh? And the present tense is tough. Not because you didn't write it well - but because I'm not used to it. I believe synopsises are written that way. Personally, I find it difficult and distracting.
Nits:
Grasp of the hostile sun. To grasp something is to hold it. How is he being held by the sun? If he's in his ship and in its gravity well or something, okay. If not, grasp may not be the right word.
Villanova approaches. This early I'd like to know who Villanova is. I think it's okay to say "his friend Villanova," or "the ship's pilot, Villanova."
Villanova approaches and I expect them to meet, then Villanova stops in front of a street vendor. I had the MC alone based on the pace of the first paragraph. He's chillin with some summery lemonade and taking his time doing it. (based on the melting ice comment) Where do street vendors fit in? This is the odd juxtaposition I refer to in my first paragraph.
Someone's going to kill Villanova with a frying pan? There's fury, but I don't know why so I don't yet care. However, I do care that Larkin is going to watch someone who is handicapped and can't defend himself get whacked and not do anything about it.
This makes me not like Larkin. Good characterization if that's what you were going for.
Granted, I don't know the next few lines. All this could get sorted out - but these are my impressions off the bat.
