Winners of the contest have a more than good chance of getting representation. It's good to enter contests, not just because you may win one, but because they force you to write short summaries and synopses, and to polish your first few pages until they shine. These are usually the only pages an agent will see before making a decision.
The contest deadline is December 31, 2016. CLICK HERE for more details.

From the GLA blog:
Welcome to the 29th (free!) “Dear Lucky Agent” Contest on the GLA blog. This is a FREE recurring online contest with agent judges and super-cool prizes. Here’s the deal: With every contest, the details are essentially the same, but the niche itself changes—meaning each contest is focused around a specific category or two. If you’re writing historical fiction, then this 29th contest is for you! The contest is live through end of day, Saturday, Dec. 31, 2016. The contest is judged by agent Elise Erickson of the Harold Ober Agency.
