Two worlds. One hidden Heart. And a secret beneath the sand that must never wake.
After a wild storm hits Ben's seaside town, he discovers a crack in the seawall - and an eerie stillness in the water below, like the ocean is holding its breath.
Then Ben meets Elizabeth... a mermaid.
Elizabeth is the newly chosen Keeper of the Heart, guardian of a living force beneath the tide that keeps two worlds in balance. Deep under the seabed run glowing "roots," ancient threads of light that anchor hidden doorways between land and sea.
But when the council announces deeper "reinforcement" pylons to protect the coastline, Ben and Elizabeth realise the terrifying truth: drilling into the seabed could strike the strongest roots... shatter the balance... and wake something ancient that has slept beneath the sand for centuries.
They can't reveal magic. They can't stop the machines by force.
So Ben and Elizabeth must attempt something even harder - convince the adults to change the plan before it's too late.
KEEPER OF TWO WORLDS is a gripping middle grade / middle reader fantasy adventure (8-12) packed with storms, secrets, underwater magic, and brave choices; perfect for readers who love hidden worlds and page-turning adventure.
