Our Happy Authors

"I am so very happy to have my new friends at Cosmos! Janet is my aspiration and had helped me throughout my publication! I am so very happy! First it was Kathrine who dealt with me and forwarded me to Janet, and Janet introduced me to the most intellectual person called Zachariah, whose inspiration drove me into writing another book! I am still in the process of writing the new book that will be titled Truth and if my present book of Time is running out and becomes a success, it will be all due to Cosmos and I salute the team of Cosmos." -

Thayil Nair

"Writercosmos has recently re-published my first novel of fiction and are half-way through publishing the second, with a third book waiting in the wings. The team looking after my manuscripts has been excellent, with great knowledge and keenness and importantly, great patience. I have been especially impressed with Associate Manager, Janet Millar who has made my journey so far really enjoyable. Her regular communications and updates are especially appreciated and her level of friendliness, helpfulness and patience outstanding, promoting my great confidence in the Company."

Dr Michael Heath

"I had a great experience working with Writercosmos on the publication of my first book. The company met all the deadlines we agreed on and showed both patience and professionalism throughout the process. A special thanks to Janet and the team for their guidance, support and encouragement along the way."

Keith Edmondson

"Janet and the crew are a hard-working group of people. They made all the revisions I requested and displayed patience and resilience throughout the project. They also guided me throughout the entire process. I am not sure they had done a Christian book before, but they strapped up their boots and dug in. We had a few failures to communicate, but that is to be expected. However, the most crucial part is that Janet and the team did not abandon me! She encouraged me to the end. However, this may not be the end, as we may work on another project together in the future. Who knows?"
