This was short and fairly straightforward (gayforward?). The story kind of skims many of its elements (like the age gap) to concentrate on the singer/songwriter aspects of their collaboration. Which works well-enough. I mean, I can't speak to the details of how collaborations like that work, but it felt engaging and I liked how it connected the two enough for me to go with the really fast attachment and the confidence-sharing intimacy.
But most of the other elements of the story were surface, at best. I mean, I have no idea what either of their backgrounds actually look like, where their families live or what they consist of, or why neither one seems to have any real friends at all. Or what they're doing with Noah as their shared manager when he turns out to be a major jackball.
So this is three stars, but on the really wobbly side of the scale. I was totally into their collaboration and shared confidences and that kept me skimming along with the author.
A note about editing: The editing on this is seriously bad. I mean, one of the leads changes names mid-paragraph a time or two (Lara? Who is Lara? Did she mean Tracy?)
A note about Steamy: There are a couple of explicit sex scenes, but in my personal definition where it counts as the same scene if all we have are stage directions between (so picking up the morning after is just a really long scene). For a book this short, that's on the edge of exceeding my steam tolerance, though not quite going past it. Some of my tolerance for the steam length is because Conway does a pretty good job with Tracy's complete lack of experience, for all she's by far the older partner.
