To the current Indonesian authorities it was a speck on the map of Maluku propinsi, included for the sake of completeness along with a thousand other uninhabited rocks. Prabir had realised the opportunity he was facing even before they’d left Calcutta, and he’d begun compiling a list of possibilities immediately, but it wasn’t a decision he could make lightly. He’d been on the island for more than a year before he finally settled on a name for it.

He tried out the word on his classmates and friends before slipping it into a conversation with his parents. His father had smiled approvingly, but then had second thoughts.

‘Why Greek? If you’re not going to use a local language … why not Bengali?’

Prabir had gazed back at him, puzzled. Names sounded dull if you understood them too easily. Why make do with a lame Big River, when you could have a majestic Rio Grande? But surely his father knew that. It was his example Prabir was following.

‘The same reason you named the butterfly in Latin.’

His mother had laughed. ‘He’s got you there!’ And his father had relented, hoisting Prabir up into the air to be spun and tickled. ‘All right, all right! Teranesia!’

But that had been before Madhusree was born, when she hadn’t been named herself (except as the much-too-literal Accidental Bulge). So Prabir stood on the beach, holding his sister up to the sky, spinning around slowly as he chanted, ‘Teranesia! Teranesia!’ Madhusree stared down at him, more interested in watching him pronounce the strange word than in taking in the panorama he was trying to present to her. Was it normal to be near-sighted at fifteen months? Prabir resolved to look it up. He lowered her to his face and kissed her noisily, then staggered, almost losing his balance. She was growing heavier much faster than he was growing stronger. His parents claimed not to be growing stronger at all, and both now refused to lift him over their heads.
