Somebody could absolutely write a 5 senses peace book.
Explanation:
Per our discussion in the comments section, a peace book is simply something that describes peace, in this case, using our senses.
You could possibly write something like a poem or something.
Peace is the dewy morning scent upon the lake, as the warmth of the light grazes the skin. Peace is the sound of the birds chirping as we watch the morning sunrise. Peace is the calming taste of my morning tea rolling across the tongue as I watch the day begin.
