Do you have a manuscript who is alone, desperately hoping to find the perfect certain someone?
Maybe manuscript matchmaking is for you!
All joking aside, you should check out MS WishList. It's a collection of hashtags detailing what various agents and publishers are looking for in a manuscript. Who knows, maybe you have written a story that fits an agent's desire.
Aside from a list of agents' wants and needs, it's also a great general resource on what works for queries and what doesn't, and how the publishing process works.
