Nathan Bransford, way at the top of my list of "agents I'd love to have", is doing a first page contest. I have posted "Seven"'s first page on his blog for the contest (go to the contest page and search for "Seven Exes" on the page to find it) and am hopeful he'll like it.
If you came here from there, feel free to leave feedback about the page. Constructive, preferably, but if you liked it (or didn't like it - but tell me why!) let me know.
I am about a day or two away from rewriting the final scene, then it's time to go through and make sure all the pieces link up properly. Can't wait. I LOVE this book!
