If your query needs some eyes before you sending it flying out into the netherworld of agents, take a look at this awesome opportunity. SC is inviting writers to send in their queries. Queries will be randomly drawn and posted on his blog so that participants can offer feedback and vote on the query "most likely to succeed." The only prize involved is the prize of a better query.
So take heed and send off your query. The deadline is Thursday, March 21st at 8:59 pm. You can find all the details here.
I've sent my latest query. Have you?
