Several days ago I received a response from the agent I submitted my revised first three chapters to. They requested the full manuscript! Maybe it's silly for me to be so excited when there's no guarantee that the agent will offer me a contract, but I can't help it. This is definitely progress.
I am also still waiting to hear back from the small publishing house which has been reviewing my full manuscript. I am taking the attitude that no news is good news--at least they haven't sent a rejection.
I can't wait to see which way God leads me. Either way (or whatever He has planned) will be exciting.
