"Working with you was a positive experience. You were responsive with communication, which is helpful. I've never published a book before, so I don't know what the normal process is. I'm wondering if there is typically a stated time frame for reading/reviewing? Not sure. As I've had to follow up with everyone who offered to review the book, it seems normal that the time frame is loose. I've reviewed a couple of books since I published mine, and I have tried to set clear deadlines with the authors, mostly because I need the deadlines for myself.
Again, thank you so much for the review. I'm happy to recommend you to author friends if you are looking to do more."
