Great premise--but the novel just doesn't deliver a plot. Just lots of meandering around the same not-so-credible angst. And when a twist is finally served up, it's handled clumsily.
I finished it at a skim.
I will say that the author has taken great care to have the book copy-edited before publication. It is not (like many others) riddled with errors.
I still have yet to find a truly satisfying rock star romance. May have to write it myself...
