Thanks guys, I wasn't sure about young adult prints as the are seems too vague -it could cover almost anything! In regards to my story, I consider it more young adult as it deals with characters that are young and their discovering of the world around them...
I am aware of ALL the big firms only accepting agent submissions -naturally as I'm guessing their slush pile must be 1000s of manuscripts high! Could I ask any advise upon the sort of agent that would be willing to view a manuscipt in this field? Would that be a general young adult agent (I try to avoid writing childrens, as that seems to be another kettle of fish entirely) or a SFF agent...
But thanks for the tips so far
