'WOW! One of the best books I have read in 2026.'

Five strangers are locked inside New York s most notorious library.

The famous author. The journalist. The professor. The bookseller. The architect.

For one night only, the library welcomes them for an exclusive after-hours tour.

They expect to see a legendary book. Instead they witness a gruesome murder.

And now they must find the killer among them before morning, or no one will survive the night
