It's Not a Bed, It's a Time Machine

In It's Not a Bed, It's a Time Machine, a clever picture book by Mickey Rapkin and Teresa Martinez, a young boy anxious for bedtime discovers his bed is a time machine!
Bedtime means lights out, with dark corners and spooky sounds. But it also means . . .
Adventure! Because it's not a bed, it's a time machine. Our hero rides it to the coolest time of all—the age of the dinosaurs. He makes a tyrannosaurus-sized friend, who helps him become the Boss of Bedtime.
While tonight's sleep will span millions of years, it'll feel like it's over in the blink of an eye.
