A forgotten necklace… A far-off land… A fantasy she never imagined…

Savannah Wood doesn’t just think she’s an ordinary twelve-year-old, she knows she is. Eager to leave the bullies that have made her life unbearable, she jumps at the chance when her father suddenly announces they’re moving to the Faroe Islands for his new job. Savannah is ready to find new adventures – especially ones that can link her to her ancestry. Her grandmother was Faroese, and when in the move Savannah’s mother unearths a sapphire necklace that belonged to her, Savannah is drawn to it, little realising that this gem will change her life forever.

For there are dark secrets hiding beneath the waters surrounding her new home. Deep in the fjords exists the Hellson, an underwater volcano ruled over by Ragnar, a merciless Viking with a craving for power. With only a secret force called The Sapphire Society to stand in his way, Ragnar will stop at nothing to claim the islands and its inhabitants for his own. Told that her grandmother was an accomplished member, Savannah throws herself into the society, nurturing her own talents and making new friends. But when the Hellson threatens to erupt and Ragnar’s army strikes, Savannah must call on all her courage to stand up to her nightmares and face the threat head-on for the sake of the island - and the entire world.
