I am a new novel writer. I want insurance to protect me from the hold harmless agreement in self-publishing agreements.

Do you have an independent agent? They can usually find any insurance for you.

If not try a professional writers association. A good place to look for one would be on LinkedIn.com

A reference librarian at your local public library will be able to give you the names of insurance companies that you can then call or maybe check their web sites to find out premium costs and deductibles.

The Encyclopedia of Associations (at the library) will also give you the name of a writers' association.
