Can’t find this book anywhere (Shadow Sun by Lani Lenore)

Shadow Sun by Lani Lenore is the final book in a dark Peter Pan trilogy that was published in 2015 by indie author Lani Lenore. I found the first two books with no problems, but I cannot find this third and final book *anywhere.* Does anyone know how I can get my hands on a copy of it? Either digital or physical?

I learned my lesson with the Game of Thrones series, and I won’t start a book series unless I have all the books beforehand. So as much as I want to read this trilogy, unless I can find the final book it’ll forever be on my TBR list.
