Can Family, Bravery, or Independence be a tone for a book? ?

Question

I understand what tone means, im just unsure whether these could be possibilities or if im stretching the limit lol...

Answer 1

youre def stretching the limit.

Answer 2

I would consider these as themes or topics.  One has to rely on setting, mood and context to create the tone of a book.  The tone could be humorous or calm for example.
