Hi M-Kenny!
I may not be the best at synopsis' but I can definitely do queries

, not trying to brag here people but I get a ton of requests for my manuscript...now the rejections that follow, that's an entirely different matter; so we'll just forget about that and move right along...
Anyhow the basic formula is this:
1. Why are you quering this agent
2. Brief description
3. Hook
4. Your title, genre, word count
5. Author bio
6. Thank you and goodbye
You've got the basic idea, you just need to tweak a couple of things as this almost comes off as a query/synopsis hybrid. With the query less is more; with the synopsis, well that depends on the agent.
Some things to leave out:
1. outcome, (leave 'em with a hook)
2. the fact that you haven't finished (they hate that - so finish up before you send these out ;))
3. bio info that has unpublished writing info, or other people's opinions
4. comparisons such as "This book is very similar to something Stephen King would write." (they hate those too)
If I were to do this really quickly (translation - don't use this without editing it) it would look like this:
my name
my address
my phone #
my email
agent's name
agent's agency name
agents address
Dear Agent,
I read on your website that you represent romance. I thought you might be interested in my novel, XXXXX.
XXXXX is a modern day love story told from the point of view of childhood lovers Marty and Diane, who were tragically torn apart in their teens by Marty's controlling mother. Now in their fifties, both had been leading wilting lives (Marty suffering through a loveless marriage and Diane recently widowed), when they stumbled across each other on the internet, igniting an old flame that had never gone out. As they struggle to connect over a 400 hundred mile gap, the fact that Diane's kids disapprove of the relationship and Marty's divorce turns violent only adds to their problems.
XXXXX is 300 pages doubled spaced and 90,000 words.
This story is reflective on my own life experiences and I would love the chance to share it.
Please let me know if you are interested in XXXXX. I have included a SASE for your convenience. Thank you and I look forward to hearing from you.
Author's Name So that's very quickly a condensed version of yours. You can use all of it, (but please edit, I'm horrible with punctuation) some of it, or none of it. I just hope I gave you some ideas. Your story sounds very interesting and I can tell just from your letter how passionate you are about it

That's great, hold on to that!
Good luck!
