This is my first 5 star in a minute and honestly it was so good and gripping and captivating that I ended the last page, read the acknowledgements, and then reread the first chapter. I don't think I have EVER done that move. Like reading a version of eternal sunshine of the spotless mind (not in content but in captivation), where you can't understand the beginning until the end but you knew that the beginning was incredible before you understood it all. 

Marvelous. Truly a masterpiece. And a DEBUT novel??? Unreal. I feel truly blessed to have encountered this. I read it in company at a book club and often would gasp, say "whatt?????", chuckle, or groan. Fully immersive. Incredible.
