Krista V. over at Mother. Write. Repeat. is hosting An Agent's Inbox Contest TODAY (12/19)!. You submit your query and first 250 words which will be evaluated by an agent. That agent will pick the winners (and prizes) the following week. Your manuscript must be complete and polished in order to enter. Accepted genres are listed in the rules, but YA is one of them. Good luck!
