Daniel is trying to shield Vera from his suspicion that their son’s fall may not have been an accident. He doesn’t know much really, only that Luke was talking to an old English professor right before it happened, a writer named Colin O’Connor who published a cult classic decades ago. Here’s what Vera knows, from years of teaching middle school science: Since Luke fell a distance of almost forty meters, he landed at a velocity of one hundred kilometers per hour. She is keeping a secret as well, a journal she found stashed among Luke’s belongings. While Vera looks for answers in her son’s journal entries, and Daniel tries to find the truth on the pages of O’Connor’s book, Luke oscillates between fighting for his life and letting go.
