“The smell of dry earth, opening to the rain in the spring. It unlocked me like a key. Once upon a time, Emmeline. "Petrichor," Rene said. "The word comes from petra, which means stones, and ichor, the ethereal blood of the Greek gods. Plants release an oil that stops their seeds from germinating when it would be too difficult to survive. The oil soaks into the pores of the stones, and is set free with water. They say it's the smell of waiting, paid off.”
