Begging for Beta

Does anyone have time in the next few days to read a 1500-word science fiction story and tell me if it's comprehensible? I'd be glad to read something in return.

It's for the Air and Nothingness call for long titles, due by March 31st, so, alas, I've left finding a beta reader down to the wire. Plus, my couple of go-to people won't work because they've already read stuff relating to these story events.

Thanks in advance to any kind taker.
