What if an entire world of MONSTERS lived underneath your floor? Martina is having trouble sleeping because she is afraid monsters might break through the floor and bring her into the monster world where she’ll have to learn how to scare humans. Meanwhile, Anitram, a little girl monster, is also having trouble sleeping. There’s a noisy little human jumping on the bed in the upside-down world under her floor! Martina and Anitram have more in common than they realize and when a mysterious hole opens up in the floor between their worlds, they are in for a big surprise! A beautiful and clever tale that makes a perfect bedtime story for anyone who is afraid of (or wants to become friends with) a monster!
