“Dina had meant to get a black cat when she'd gone to the cat shelter a few years ago; she loved the way they looked like little pockets of midnight. But then she'd heard a grumpy yowling coming from a small cage near her feet. "That one's just come in, the vet reckons it's a feral one. No microchip," the man who worked there had said. Dina had crouched down and locked eyes with the cat, who was mostly black but with a golden crescent shape on top of her head and a creamy white belly. Heebie, who hadn't even had a name then, had bumped Dina's outstretched knuckle with her head, and Dina had felt the warmth of the cat's cheek and known instantly that she had found her familiar.”
