Alex Neptune is back for his most epic adventure in this fifth and final instalment of the action-packed series - perfect for fans of Percy Jackson and Dragon Realm!



Brineblood the pirate is back on the high seas with a dastardly plan - he's going to steal every drop of sea magic and use it to raise an all-powerful monster from the bottom of the ocean. If Alex, Zoey and Anil can't stop him, the monster could flood the entire world.



Teaming up with the water dragon, they use a home-made submarine to journey deep into places no human has been before. But they have one crucial problem: Alex has lost his magic. Can he still lead his crew to victory? Or will Haven Bay - and the rest of the world - be lost for good?



Having worked as a freelance games journalist and taught on a BA Creative Writing course for three years, David Owen's debut novel, Panther, was longlisted for the Carnegie Medal, and was followed by three further highly acclaimed YA novels. Alex Neptune is his first series for younger readers, born of his love for nail-biting heists, fantastical monsters and heartfelt friendships.
