One Thin Patch of Ice

"My sister - Penelope. Four years younger and better at almost everything. We had a lake by our cottage, and in the winter it'd freeze over. And we must've spent hours, days even, out on that lake. But all it takes is one second, one thin patch of ice and your whole life changes forever." This is the story of how Will lost his sister, Penelope. Set before OUATW.
