Hello!
The difference between <em>tone</em> and <em>mood </em>is:

____________________________________________________________
Tone:
Tone is what the <em>author </em>feels about what s/he is writing. It reflects the writer's feelings.
Mood:
Mood is what the <em>reader </em>feels about what s/he is reading. It is intended to shape the reader's emotional response to the literary work.
<em>Sometimes </em>the mood and tone can be the same. This isn't always the case, though.
