Houdini the octopus lives in an aquarium, but she misses her home in the wild Sea.

She doesn’t like the visitors who bang on her tank. Or the way she can’t feel the sun on her skin or the wind rippling the water. It’s a dull existence for a creature with nine brains.

Then one day she meets someone who is different to the other visitors. Juno’s busy brain buzzes with so many questions and thoughts that Houdini’s skin tingles with wonder.

But the singing of the Sea is growing stronger and harder to resist. Can Houdini make Juno understand what she needs before it’s too late?
