If you are a writer (or want to be) and you don’t know who Kristen Lamb is, you should. Full disclosure: she is selling books and services (SHOCKER I know) and I have neither taken anything for this endorsement nor partaken of her services (though I perhaps should). The article linked below is encouragement on why we should accept the drudgery of writing a synopsis whether we are looking for a traditional publishing agent or an indie publishing author.
Click through to her site and check out the article. If nothing else, it is an entertaining lead filled with good advice like not trying to pay an agent in cute goats or putting glitter in your query letter. I second both of those pieces of advice by the way.
