As with most of Andrew Grey's work, this is another fairly feel-good contemporary of how people can come together under special circumstances. 
 I have to admit that I really like the theme of this particular series (each has an MC unable to use one of the five senses), and I'd been wanting to read a story with a character unable to speak, so this hit a chord with me immediately. 
 The author gently handles the circumstances of Hanna's disease and their lives, as is typical of an Andrew Grey story. It is not super angsty, but it gets the point across that one man has a complex about his inability to vocally communicate (and how he's withdrawn from society), and the other about his ability to commit to a relationship when all of his efforts go into being strong for his daughter during her difficult treatments. 
 If I have any complaint, it's that Ken's ex suddenly disappears from the story, even though he supposedly cares about Hanna even still. I didn't expect any sort of major confrontation scene (in fact, I was glad there wasn't one), but I did expect to see Mark come around for Hanna (or to at least make his apologies that he didn't feel like he could), and it didn't sit right that he completely vanished from the story. I didn't feel that part received full closure, I guess. 
 Otherwise, I enjoyed it.
