Grace and Scott are likeable and relatable protagonists (not that I've ever been a celebrity with drug problems, or ever worked in Hollywood at all, but hey...).
Their story feels real, and I love seeing their relationship grow from mutual dislike into something bordering on respect, then a tentative friendship, and then - finally! - into so much more.
The problems and hang-ups they face are realistic and dealt with in a grown-up manner.
This is the first book in the series I have read, but now Rising Star is definitely on my TBR pile!
