Dear Miss. Snark,
An agent read my partial and has requested the full manuscript (oh joy!). Since I was diligently writing another book (not a sequel) while my query made the rounds, I now have a second book to offer. These are chapter books for children and while all the writing rules apply, the relatively modest word count means I can be productive. As an unpublished, unagented writer, I intend to send the agent the requested ms with a thank-you and copy of her request. I am wondering if I should briefly mention other projects in my coverletter?
I want the agent to know I'm committed and productive, not a one-trick-pony. Yet I don't want to be tossed in the pile of nitwits-who-think-I'll-want-all-their-work-right-away.
You're safe. Mention the other work. Briefly.
The "don't overwhelm me with tales of your output" advice is generally for those of you working on big ass novels who have a sixteen part series all ready to go.
Kids chapter books are hard to write, in part because the word count is so low, but many very very fine writers produce more than one a year. I miss Paula Danziger a whole lot.
