To err is human

Oh well. I guess I am not the only one who has passed through this step. I still consider myself a beginner in the publishing industry, and this kind of mistake is easy to make.
What I am talking about is the re-issuing of the second book I have ever published, "The Ghosts of Morgan Street."
In the beginning, I gave the editing work to someone who had great feedback about her turnaround times and quality of work. Particularly the latter impressed me, so without even caring about the price, I chose her.
Now, and only now, I start to reconsider that the job was not done correctly. Particularly after having found a new editor who did a fantastic job with Aquila et Noctua, I decided to give her the task to re-edit the work.
Better later than never.
Anyway, I am considering to go through all the other books, including the trilogy, and see how can I improve them.
Of course, there couldn't be any re-edition without dressing the book for the party with a brand new cover. That was perhaps another problem that could have resulted in poor sales. Using the blessed time of being alone for the whole week in the house, I put myself to work. Then, with the help with the best purchase ever, a drawing tablet, I started to combine, cut, draw, and color, until I could reach a satisfying result.
Of course, you would like to see it, and here it is:

It is nothing fancy; actually, I kept it as simple as possible, making it more compliant with the standard for the genre, psychological thriller.
Any feedback is welcome.
The re-release will come in the following week, so it's a good time to stay tuned and hope for the best.
So another thing I have been learning is the importance of not just choosing a good editor, but the one that can work with the kind of issue that most likely is affecting your writing.
For example, my problem is not being a native speaker and finding a person who is qualified for editing works of people who have English as a second language, is critical.
Every writer has a particular issue, whether it is a problem of plot holes, stilted dialogues, or anything else, finding the right editor is crucial.
Of course, this means also going through a list of wrong editors. So far, I changed four editors before finding the right one. Therefore, if you are in the same situation as I am now, and are wondering whether your editor is the right one, I suggest following more closely what the readers say and how do they react to everything you are publishing. They are, at least from my point of view, the best channel to understand whether what you are doing is right.
That said, I wish you all a great weekend and see you next week.
