So I used to be very active on this site when I was querying back in 2012/2013. Long story short...I got an agent. That book didn't sell. I wrote another one. That one sold in a 2 book deal to a small publisher. I wrote the sequel. The first book was released. Then the publisher had some trouble/legal issues etc. I decided to get the rights reverted back to me and not publish the second book with them. After all that drama, my agent decided to stop being an agent. So that was about a year and half ago. I went back to school and took a break from writing but now that I'm getting back into it I have some questions.
I am currently re writing the first book I wrote that didn't sell but the two that sold are in very solid shape. Is it bad idea to try to query a new agent with the two strong books even though one of them was released (epub only and is no longer available) for a short time? Should I just forgot about those two and focus on querying the first book that I'm rewriting? I'm not sure what the dos and don'ts are in this situation. Any insight would be helpful. Thanks in advance.
