In the Middle of the Night. Riley Sager

Summer 1994, New Jersey, USA. In the backyard of a house on one of the most prestigious streets in the country, two ten-year-old friends spend the night in a tent - this is their tradition. However, one morning only one boy, Ethan, woke up, and the other, Billy, disappeared without a trace.

This area is inhabited exclusively by wealthy and successful scientists, engineers, bankers, who have everything they want. Could it be that one of them sneaked into the yard at night, cut open the tent and kidnapped the defenseless boy? But why?
