QUOTE : in Jackson’s palm, as if it were a gift—Jackson was reminded of his biology teacher from school who would hand you something—a bird’s egg, a leaf—and make you explain it to him rather than the other way round. The rock was a dark ironstone that looked like petrified tree-bark, and sandwiched in the center of it was a seam of milky opal, like a hazy summer sky at dawn. A notoriously tricky stone to work, the old man informed Jackson. He had been looking at it for two weeks now, he said, another two weeks and he might be ready to start cutting it, and Jackson said that in another two weeks he would be in a remand prison somewhere, but the guy had a great lawyer and made bail and got away with a suspended sentence. A year later Jackson received a parcel addressed to him at the police station. Inside there was no note, just a box, and in a nest lined with midnight-blue velvet was an opal pendant, a little plaque of sky. Jackson knew he was being given a lesson by the old man, but it had taken him many years to understand it. He was keeping the pendant for Marlee’s eighteenth birthday.
