It was during those weeks, in the slow accumulation of sketches and shore walks, that Tess's idea for a mural began to form, though at first she did not call it an idea at all. She thought of it as a picture that kept returning to her: a tide pool at low tide, seen from just above, as if the viewer were kneeling on the rocks looking down. In the picture there was a starfish, orange and patient, spread across a flat stone. There was a hermit crab, half in and half out of its borrowed shell, making its careful way across the sand. There was seaweed, green and brown, drifting in the shallow water, and, tucked into a shadowed corner, a small anemone, its tentacles open like a flower that only bloomed underwater. It was not a grand scene. It was a small, complete world, and Tess liked that about it. It said that what was left behind when the tide went out was not empty or abandoned, but full of life, if you knew how to look.
She did not tell anyone about it at first, not even Mara. She worked on it in private, in the margins of her sketchbook and then on larger sheets of paper spread across the kitchen table late in the evening, after Elena had gone to work and Mara was doing homework or out running. She tried different compositions, moving the starfish to the left and then to the right, making the pool larger, then smaller, then larger again. She tried painting the water as a pale, glassy blue, and then as a deeper green, the colour it was on a cloudy day. She painted the rocks in greys and browns, with touches of pink where the barnacles clustered, and she learned, through trial and error, how to leave white paper showing through for the light on the water's surface. Some evenings the painting went well and she felt a lift of excitement, as if she were discovering something. Other evenings it went badly, the colours muddied or the crab looked wrong, and she had to put her brush down and walk away before she spoiled it by overworking it.
Mara noticed, in the way sisters notice things without being told, that Tess was working on something that mattered to her. She noticed the way Tess guarded her folder, the way she stayed up a little later, the way she was quieter than usual at dinner, thinking. Mara's first instinct, as always, was to help by stepping in, by offering to carry the thing, to fix it, to make it easier. She caught herself doing it one evening when she said, "Do you want me to tell Ms. Alvarez how good it is?" and Tess had smiled, a little tiredly, and said, "I can tell her myself, when it is ready." Mara felt a small sting at that, not because Tess was unkind, but because Mara was used to being the one who spoke up, who ran ahead, who cleared the path. She sat with the feeling for a while, and then she did something that felt both smaller and harder: she made Tess a cup of tea, put it beside her painting without comment, and went back to her own homework. Tess looked up, surprised, and then grateful, and Mara understood, in a way she had not quite put into words before, that help did not always mean taking over.
Their daily life continued around the painting, in the ordinary rhythms that held the family together. Elena's shifts rotated, and on her days off she cooked large, comforting meals, a stew that simmered all afternoon, or pasta with vegetables from the market, and the three of them ate together at the kitchen table, talking about their days. Elena asked Tess about the marine centre and Mara about hockey, and she listened to both with the same attentive care, even when she was tired. On weekends, when the weather allowed, Mara went for long runs along the coastal path, her breath coming in steady rhythm, her feet finding the familiar stones, while Tess walked the shore with June, collecting nothing but sketches and observations. In the evenings they sometimes watched a film together, Mara sprawled on the sofa with a blanket, Tess curled in the armchair with her sketchbook on her knee, Elena dozing between them after a shift, waking just enough to laugh at the funny parts.
