When Tiger and Luna get sucked into the fantastic frame this time, their destination is the diner depicted in Edward Hopper's famous painting Nighthawks. They explore the streets of New York in 1942 and ride the subway through the dark underground tunnels. It's another art adventure for Tiger and Luna, and as always, they must find their way back to the real world before it's too late—or remain stuck in the painting forever. Praise for Danger!
