So this is the latest synopsis of my book:
As revealed in the later part of the 5th para of the synopsis, Vasitva (= ability to subdue and control) is a the name of a Siddhi (= achieved ability).
The book is supposed to be the first in a series.
My initial idea was to name the series as Siddhi, with this book being called Vasitva.
However, I agree with other comments that this might not click with the global audience easily.
So the question is a two parter:
1. Is Siddhi, the right name for the series?
2. Is Vasitva, the right name for the book?
