A literary agent is your advocate inside the publishing industry. They pitch your manuscript to editors, negotiate your contracts, and stay with you across the long arc of your career. A good agent already knows which editors are hunting for your kind of book, how to position your work when the market feels crowded, and how to protect your rights the moment offers start coming in.

Publishing your book without an agent is entirely possible. For authors chasing a traditional deal, the right agent reaches editors and rooms that stay closed to most writers working alone.
