When you search for this "author" on Google, you have to be sure to put it in quotes and when it tries to correct the last name to "HEUghan" you have to tell it no, stick to the way I typed it.
Then you get more Amazon "biography" results such as this one -
https://www.amazon.com/Prince-Harry-Book-Biography-ebook/dp/B0BKWWPPGV
"Dan Hueghan returns with a captivating biography of one of history's most remarkable men, Prince Harry." [a bunch of crap was here, and then it ends with:] "This book is a story about the life of a man who is changing the world the way no one else can."
The cover is identical to the one about Jinger except with a different picture and book name of course, and it has four ratings of one star lol.
