Several months ago, I sent out some query letters for my book Henry Rider: Clown Hunter. Since then, I became unsatisfied with the final battle and ending I'd written, and I've been rewriting it over the past few weeks. Just a few hours ago, though, one of the agents got back to me saying they wanted to see more of the book (cue very un-masculine squeal). Problem is, the query I sent them had a two page summary of the book as it was back then. Is it okay for me to give them the rewritten version if they request the whole book, or do I need to give them the old version that I described in the summary?
