In the northwest the sun had broken around the lower slope of Midsummer Mountain and was sending a last long wink across the Sawtooths, straight into the black mass of rain cloud. Clear across the stone house, bridging from mountains to river bluffs, curved two rainbows, one above the other, even the upper one as bright as colored glass, sharp-edged, perfect from horizon to horizon.
Oh God. What does this mean?
After I stopped laughing, I couldn't take the book seriously anymore so I spent the rest of the day watching Double Rainbow parodies. Enjoy.
