Gray is already bigger than all the other sharks in his clan and his hunt for food forces him and best friend Barkley to journey deep into the dangerous Big Blue. Who can Gray and Barkley trust when the ocean is full of slippery fish - and one mistake means you're someone else's dinner? A brilliantly exciting new title to follow 'Shark Wars', perfect for boys and girls of 8+, fans of 'Beast Quest' and those ready to move onto something more sophisticated.
