Here's a breakdown:
* Mood: This refers to the overall feeling or emotion that the reader experiences while reading the book. It's the emotional impact of the story. Examples include: suspenseful, cheerful, melancholic, hopeful, or eerie.
* Tone: This refers to the author's attitude towards the subject matter. It's the author's voice and how they convey the story. Examples include: serious, humorous, cynical, ironic, or sentimental.
While mood and tone are closely related, they are not the same thing. Mood is what the reader feels, while tone is how the author expresses their feelings.
