I became his first love and the mother of his first child and, as such, I have a unique perceptive to share on this man who has fascinated the world.
It is taken from the NOTE TO THE READER section of the book The Bite in the Apple by Chrisann Brennan.
I'm unable to understand the usage of the word perceptive in this context. I think it could be a typo(perhaps should be the word perspective?) by the author. However, I've seen such usage of perceptive over and over again in the same book so I'm even more confused.
