Double Danger. Summer Waters

      Bubbles stared at Cai with his mouth open. “Humans,” he clicked, slowly shaking his head. “You make things so complicated.”

      Antonia and Cai laughed loudly.

      “Too right,” said Cai.

      Spirit helped the Silver Dolphins swim the shopping trolley towards Claudia’s beach. Bubbles swam alongside, occasionally turning somersaults or suddenly diving underneath the trolley.

      “Bubbles!” said Star in a warning tone. “I’ll take you out to sea if you don’t behave.”

      Bubbles rolled his eyes when his mother wasn’t looking and Antonia stifled a giggle. Star was as strict as her own mother, but she loved them both dearly. Thinking about Mum made Antonia uneasy. How long had they been gone? It was difficult to gauge time when she was a Silver Dolphin. And, although it seemed to go more slowly, Antonia was worried that she might be so late for school she’d need a better excuse than forgetting her lunchbox.

      At last, Claudia’s beach came into view. There was lots of nose-rubbing and ruffling hair with flippers as the dolphins said goodbye. Bubbles high-fived Antonia and Cai with his tail.

      The Silver Dolphins dragged the trolley ashore. It was even more awkward to move on land than it had been in the sea. The sand jammed the trolley’s wheels until eventually they gave up trying to push it and carried it over to the Sea Watch boat. Antonia pulled a hair-tie out of the pocket in her dress and swept her damp hair into a ponytail. It was the only thing to show she’d been swimming in the sea. The Silver Dolphin magic had left her clothes as dry as if she’d been sunbathing.

      “Hopefully no one will notice my wet hair,” she said.

      “I’m sure they won’t,” agreed Cai, pulling on his shoes. “Where did you leave your shoes? We’ll ask Aunty Claudia to take us there in the car before she drops us at school.”

      Antonia brightened. “Thanks,” she said. “It’ll be quicker than walking.”

       Chapter Three

      Claudia drove Antonia to Gull Bay and then on to school. She left Cai at home, promising to take him in later.

      “It’ll look suspicious if you both arrive late together,” she said, her sea-green eyes twinkling.

      School had not long started, but Antonia had missed the register and Miss Brown sent her to the office to see Mrs Lee, who was in charge of signing in latecomers. Antonia smiled cheerfully at her mother, but Mrs Lee gave her a stern telling-off.

      “Don’t ever do that again,” she ranted. “You are supposed to walk straight to school. If I can’t trust you to go where we’ve agreed, then you won’t be allowed out alone.”

      “I only went home to get my lunchbox. I asked Sophie to tell you where I was going,” Antonia protested.

      “That’s not the point!” said Mrs Lee. “You’ve been gone ages. What took you so long?”

      “I got a stitch from running,” mumbled Antonia. She hated telling lies, but being a Silver Dolphin meant making difficult choices.

      “I’m grounding you this afternoon,” said Mum, when she eventually ran out of things to say. “Meet me here after school. I’ll walk you home with Jessica.”

      “Mum!” exclaimed Antonia. “You can’t ground me. I promised I’d go to Sea Watch. We’re getting the guillemots ready for their release back into the wild.”

      The guillemots had been at Sea Watch for several weeks, since a minor oil spill in Sandy Bay damaged their feathers.

      “Sea Watch will survive without you for one afternoon,” said Mum firmly. “Now go back to class. You’ve wasted enough lesson time already.”

      Cai was disappointed that Antonia wasn’t allowed to go to Sea Watch, but Sophie was pleased.

      “Can I come home with you?” she asked. “We haven’t been round to each other’s houses after school for ages.”

      Antonia’s face reddened. “I’d love you to. I don’t want you to think that you can only come round when I’m not allowed to go to Sea Watch, though.”

      “Don’t be silly,” said Sophie. “We’re better friends than that!”

      Jessica, Antonia’s little sister, was ecstatic to have both Antonia and Sophie walking home with her.

      “Can I play with you?” she asked. “I’m seven now. It was my birthday when you were away, Sophie.”

      “I know,” said Sophie. “I can’t believe you’ll soon be in Year Three.”

      “So can I play with you?”

      “For a little bit,” said Sophie kindly.

      At home, Antonia took Sophie straight up to her bedroom. Sophie’s gift from the Jersey pottery was a beautiful dolphin figurine with a blue and gold glaze. Antonia put it in pride of place on her dressing table. They talked for ages, mostly about Sophie’s holiday in Jersey. Sophie also had her sketch book with her and showed Antonia some of the sketches she’d done for her latest art project: painting pictures of the cats that roamed around Sandy Bay. Then Jessica came barging in, demanding that the girls played with her too. She wanted to play hide-and-seek, so everyone went outside to hide in the garden. Sophie played four games before deciding she’d better go home. Antonia went to the side gate with her to wave goodbye and Jessica trailed after them. When Sophie had gone, she followed Antonia indoors and upstairs to her bedroom.

      “You like dolphins, don’t you?” she asked, noticing the present from Sophie on the dressing table.

      “They’re my favourite animal,” Antonia agreed as she pulled her swimming bag out of the cupboard. It was squad night. Luckily Mum hadn’t grounded her for that too! Antonia packed her bag with the things she needed.

      “Is it because you swim like a dolphin?”

      Antonia’s heart missed a beat as she spun round to face her sister. What did Jessica mean?

      “Naomi’s sister is in your class at school. She calls you the dolphin girl because you’re brilliant at swimming.”

      “Oh!” Antonia smiled. For a wild moment, she thought Jessica had discovered the secret of the Silver Dolphins.

      “Can I try your necklace on?” asked Jessica, reaching out to touch it.

      Antonia drew back. “No, Jess, you know my necklace is special.”

      “Please,” begged Jessica, making her green eyes go wide. “I want to see if the magic works for me too.”

      There was a funny rushing sound in Antonia’s head. She tried to speak, but her mouth was so dry that her voice came out in a croak.

      “What do you mean?”

      “I know your dolphin charm is magic. Ages ago, you said it made you swim better,” said Jessica innocently.

      Antonia met Jessica’s eyes, choosing her words carefully as she spoke. “My charm isn’t magic. It’s lucky. It gives me confidence, so I swim better when I’m wearing it.”

      “Can I touch it then,” said Jessica, “for luck?”

      “No.” Antonia quickly hid the dolphin charm inside the collar of her school dress.

      “You’re mean!” Jessica’s eyes welled up with tears.

      Antonia was suddenly ashamed of herself.

      “Don’t cry,” she said, hugging Jessica’s stiff little body. “I’m not being mean. This is my lucky charm. The luck only works for me. You’ll have to find your own thing. Why do
