"OnlineBookPublicity under the direction of Hanji is run professionally and with intention to succeed. It is a fabulous service and a must for all authors, and after many years with them it is obvious to me that their publicity has been instrumental in my achievement as a #1 bestseller and award winning author. It has been my pleasure to refer many other author friends to this company, which is my highest compliment. Thank you Hanji for the good work that you do for us!" - Amazon Best Selling Author - Nora D'Ecclesis
