I recommend working with the team at GWP. Adam as my project manager has been very patient and helpful throughout the process. The illustrations the team has done have been excellent. They helped me sketch out developmental edits for my series, guided me as I wrote the book, and then helped me polish the final edits. I appreciate everyone on the team. Great job, looking forward to book 2!

Engagement from Jonathan was great, he promptly followed up on all milestones for my audio book recording and worked to take my feedback. I would give 5 stars to him, but the delays caused by the project over all due to artist delays I had to mark it down to 3.

Ghost Writing Proficiency really came through for me in helping me write my first book. They were very quick on making the changes I requested and kept in touch letting me know each detail of the process. This was my first book and I'm very happy to have chosen them to help me!

The team led by Isacc Leo has been very supportive of all my needs. They have helped me write about a difficult subject and have allowed me total input every step of the way. Nothing is a problem for Issac. He listens and gets the job done promptly. They have also helped me with my website and marketing. I thank all members of the team. Well done!
