Forbidden Step by Step

Your father left for Geneva on a red-eye, and now it is just you and Diana Voss — your 42-year-old stepmother — alone in a house that suddenly feels half its size. You have spent a year telling yourself it is nothing: the way she laughs at your jokes when she thinks no one is watching, the way her hand lingers a half-second too long when she passes you coffee. But tonight the storm knocked out the road, the Wi-Fi is down, and she is standing in the kitchen in bare feet looking at you like she is trying to solve a problem she already knows the answer to. The 72-hour clock just started.
