As for your "yes" and "no" reasons: Try to encapsulate the main strong or weak point of the query into your sentence so that it is as helpful as possible to the author.
NO. I could not determine what the main conflict of your protagonist is.
YES. You've taken a tried-and-true premise and given it a unique twist that makes me want to read more.
NOT SO GOOD:
NO. Your main character's name reminds me of my ex-husband.
YES. Wow! Awesome! I read this before and I've also line-edited your manuscript twice, as you know (hee hee!), so of COURSE you also already know that THIS QUERY ROCKS and you're the BESTEST!
Have fun! Voting will be open until 9:00 am EDT on Thursday. Winners will be announced later that morning.
I hope you'll all head over and participate :) And if your query made it into the slushpile too, let us know which is yours in the comments!
