This was the perfect conclusion to 죽이고 싶은 아이 that I didn't know I needed. As the author says in the note at the end, the tones of the two books are quite different: Book 1 deals with the distinction between lies and truth and is a thriller/mystery. In contrast, book 2 focuses on the aftermath of the murder case, the destruction of people's lives, and how they move forward in the face of such events.
This book was gripping in a different way from the first one. The beginning was more of a mystery, but it shifted into a human drama with elements of the supernatural, mental illness, and the duties we have to ourselves and our families. The characters felt complex and fully realized, with logical dilemmas and difficulties in communicating and making choices, despite the story's unique setup.
I was quite satisfied with the book's conclusion. If you enjoyed book 1, book 2 is a must-read! 5 stars.
