As an unpublished / unagented writer (I’m not using the term ‘author’, as I reserve it for writers who have been published) it is always interesting to look at query letters that actually worked, one of which can be found at Pub Rants, a blog by Agent Kristen (whom I had the pleasure of meeting at this year’s NASFIC).

Kristen follows up with additional discussions here and here. The second post includes the letter to the editor that to getting the book published.
