The Comeback is Ariadne Hui's story. She is a young, Canadian woman who lives and works in Toronto. She starts dating her roommate's cousin and grows quite attached to him before discovering he's a pop star—actually a K-pop idol. This novel could be seen as two books in one, with the first half about Ariadne before she learns Jihoon's full story and the second about her dealing with the crazy fans of a famous person.
I don't know much about K-pop so I found this book fascinating. It delves into the problems for the musicians in those groups, not only the crazy fans but also the corporate control and the lack of respect from other musicians.
I enjoyed the multiple relationship problems that occurred throughout the story. Hannah (who is Ariadne's roommate) and Hannah's mother have some issues. Ariadne has issues with her sister, Phoebe, and both Phoebe and Ariadne have issues with their father. Throw those together with the problems of dating somebody famous and you've got a lot to work through.
When the book starts, Ariadne is a successful lawyer who wants to make partner in her firm but has to deal with racism and nepotism. It's fun to see how she handles her career while in a difficult relationship.
