Daisy works nights. Nate works days. But maybe they aren’t as different as they assume.

Daisy is the night security guard at England’s Manchester Museum of Social History. She takes her job very seriously, protecting the museum from teenage troublemakers.

Nate works the day shift, though he would be more suited as a museum guide the way he chats with the visitors. Daisy doesn’t approve: How does he find it so easy to talk to strangers?

For five minutes each day, their shifts overlap at handover. It’s the only interaction they have—until mysterious things begin to happen at the museum. Daisy notices priceless objects going missing and then reappearing, with no explanation and with nothing on the security footage. No one believes her except Nate, and he agrees to help her investigate.

They soon discover they have a lot more in common than they realized—and their investigation uncovers not only the truth, but new possibilities for their future.
