Mkuu Arnold Ndosi,
Congratulations, and i encourage you to the plan you have but yet consider the following;
1. Grammar,- really, pls review your title, earlier i thought it was a typing error, but it was consistent as it is evidently seen in your second sentence and so forth.
2. The use of capitalization of letters, really though am not linguistic but all i know you dont capitalize when you just feel like you shoud.
3. There is a big problem in the use of punctuation marks (when , how to use them)...please consider that too.
Anyway, other Great thinkers(GT) will come ahead to help and advice as you asked...Take the criticism constructively if you really want to hit "Bestseller" novelist.
