Sorry try this :-
The day the new people moved into the house behind the hill, the ocean went crazy.
Cathy was walking on the shore when the water suddenly rumbled and swelled in the windless early September morning. Waves crashed against the shore, so powerful that the sand vibrated.
A bloodcurdling scream pierced the air. Cathy turned toward the sound to see a boy of about seven struggling against the current, his face twisted in terror.
She rushed into the water gasping at the ferocity of the current. A waved slammed against her chest, sending her stumbling backwards onto the shore, knocking her into the sand.
Through the roar of the ocean,crashing waves, bare running footsteps on wet sand and the boy's terrified screams,there was another more unusual sound, that of dolphins trilling and whistling.
For one insane moment, she was sure that dolphins and sharks had washed onto the shore.
She clamboured to her feet. A silhouette appeared in the spray that leapt from the ocean. It took her a moment to realize it was a boy of about sixteen. He was looking transfixedly into the water, imitating a dolphin. She had never heard a human make such sounds before.
'He's drowning!For God sakes help him!'
She closed the distance between them in a few quick steps.
"Don’t disturb my concentration."
He stepped closer to the water, walking on the balls of his feet like a cat, his feet barely touching the sand. "I'm trying to communicate."
The little boy was spinning in a whirlpool and he was trying to communicate? Rage shot through her body like an electrical jolt but before she could respond there was the sound of a freight train coming from the ocean. She screamed when she saw what it was.
A tornado of water rose above the huge waves and hurtled onto the shore, slamming into the lifeguard's hut a few feet away. The roof shot toward the white glare of the sky. The stairs and bannisters splintered and gone. Chunks of metal and wood swirled around madly.
Then she saw dark shapes appear in the water, blurry under the raging foam. Sharks. They were swimming toward the boy who was swirling around so fast, he became a blur of dark hair and the light blue of his swimming suit.
She bolted toward the water and froze in her tracks as a dolphin's head popped out of the water, sleek and glistering in the blinding sunrays. The dolphins reached the boy and hoisted him up. He clung to one, too terrified to scream as the dolphins swam to shore, toward the lifeguard who stood knee-deep in the water, barely keeping his footing in the monstrous current. He snatched the child from the dolphin and ran toward her.
"You two." He looked from her to the boy she'd almost punched. "Away. Now. Away from the water."
There was a crazed look in the lifeguard's eyes as he stared into the ocean. Cathy followed his gaze, and for a second, she couldn’t breathe or move.
The ocean was receding, exposing wet sand that stretched toward the horizon, covered with withering fish and sealife. A tsunami.
