It's not every day a couple of eagles pay you a visit in the middle of the night and tell you your friend, who happens to be hundreds of miles away, is in terrible danger. But Matt and Elena are not everyday people. They're Night Speakers, with the ability to communicate with animals, and an uncanny habit of getting into save-the-world situations.

But what is shaking the birds' world so much that it would drive them to fly hundreds of miles? Something huge and horrifying is happening, and Tima is in the middle of it. Can Matt and Elena get to her in time? Something is going on below the surface, and only the Night Speakers can stop us all from falling into the cracks. . .

The fourth standalone adventure in the Night Speakers series - action adventures about contemporary children with extraordinary powers, told with award-winning author Ali Sparkes's classic humour and energy.
