More like 2.5. I wanted to like this so much and the first few chapters really shone but the story drifted and it felt more like the authors were trying to create "drawn from real life" after that instead of a book that stood on its own merits. Secondary characters were shortchanged but none so much as Prince Nick. 
 The writing was competent, the characters were infuriating, and (surprisingly for a book that's "drawn from headlines") the worldbuilding was minimal, as if the authors were afraid to create too much that distracted from "pssst they're really William and Kate pssssst". 
 By sticking to someone else's narrative they lost what was special, which was mostly highlighted in the early section with a vulnerable love interest, a protagonist finding herself, and many many episodes of Devour.
