A first-time author definitely needs to have a completed manuscript in hand before sending out queries. A lot of people have ideas for novels but never actually get them written -- an agent only wants to deal with people who have shown they can actually complete the writing process.
Generally it goes like this:
- write a novel
- send out queries (with the first 5 pages of the novel, or whatever the particular agent asks for -- it's critically important to follow his or her instructions)
- if the agent likes your query, he or she will request a "partial", which will be something like the first 3 chapters or 50 pages of your novel
- if the agent likes your partial, he or she will request the full manuscript
- if the agent likes the full manuscript, he or she will offer representation in selling your novel
- agent contacts editors and tries to sell your novel for you
What type of novel are you planning to write?
