Penguin Publishing Experts is covering each domain of the e-books and it’s truly impressive. I got my biography book written from them. They covered each part of it with zero errors and whenever I asked them to change something, they would do it without any arguments, considering that I made many changes when the project was at the completion stage. I received a sweetheart of a project manager who advised I should get my book published and marketed by them. Obviously it wasn’t a difficult decision since they did my previous work perfectly. I don’t regret that decision at all.
