Nancy, Bess, and George must find the truth behind a photographic mystery in this nineteenth book of the Nancy Drew Diaries, a fresh approach to the classic mystery series.

Nancy and her friends are spending the weekend in a small mountainside town called Shady Oaks. The local museum is displaying a never-before-seen collection from famous nature photographer, Christopher DeSantos. So the usually sleepy town is now filled with tourists. But it's not just the dramatic lighting of the old black and white photographs that people have come to see.

Newspapers all over the country have picked up the story of two visitors who went missing in Shady Oaks only to turn up in the old DeSantos photographs, seemingly frozen in time. What's more, there was a rumor that DeSantos was cursed by his former partner after a disagreement. Now everyone is wondering if the legend is real.

Nancy, Bess, and George are convinced that there is another explanation to be found. But it quickly becomes clear that someone is making sure they don't find it. Can these three teenage sleuths solve this mystery before it's too late?
