When Fionn Boyle sets foot on Arranmore Island, it begins to stir beneath his feet ...

Once in a generation, Arranmore Island chooses a new Storm Keeper to wield its power and keep its magic safe from enemies. The time has come for Fionn’s grandfather, a secretive and eccentric old man, to step down. Soon, a new Keeper will rise.

But, deep underground, someone has been waiting for Fionn. As the battle to become the island’s next champion rages, a more sinister magic is waking up, intent on rekindling an ancient war.

The Lost Tide Warriors

'Doyle’s talent for creating windswept, stormy tension and physical threat sweeps all before it. This is one for a seaside holiday, whatever the weather’ The Daily Mail

In the brilliant sequel to The Storm Keeper's Island, winner of the Books are My Bag Readers Award, Fionn Boyle finds himself at the heart of the fight for the island's survival.

Fionn Boyle has been Storm Keeper of Arranmore for less than six months when thousands of terrifying Soulstalkers arrive on the island. The empty-eyed followers of the dreaded sorceress Morrigan have come to raise their leader and Fionn is powerless to stop them. The Storm Keeper’s magic has deserted him and with his grandfather’s memory waning, Fionn must rely on his friends Shelby and Sam to help him summon Dagda’s army of merrows.

But nobody else believes the ferocious sea creatures even exist. And how can he prove he’s right without any magic? As Fionn begins his search for the lost army, the other islanders prepare for invasion. The battle to save Arranmore has begun.
