I'm admittedly still a little wishy-washy on what exactly agents are looking for, but I've seen one agent who is looking for "a one sentence summary of your MS" along with the query, and another who asks for a "3-5 line pitch", so I figured it's high time I put together something so that I'm not limiting myself on agents. I'm throwing out a couple ideas, but please feel free to rip them apart, because I just need to get a baseline going. I'm definitely not convinced on some of my phraseology myself. Also, if you provide a link, I will reciprocate feedback on your queries/synopses/etc.
1) Steampunk meets space opera when the captain of a worlds-traversing airship must battle a renegade with a device that can destroy society.
2) Treasure hunter. Lock picker. Captain of a worlds-traversing airship. Lara’s got the skills to save the worlds, which is just as well, because a military renegade has plans to destroy them.
