ay ruby

Lea never took her eyes off me. She lifted her empty palm, closed her fingers over it, and opened them again.
A small, gleaming ruby, bright as a drop of blood, carved in a pentagon, lay in her hand.
"It is the sum of her knowledge of the Ways," Lea said quietly. "Every path, every shortcut, every connection. She developed enough skill at searching them out that she was eventually able to predict them. Ways may change from decade to decade, but your mother knew where they were and where they would be. Very few of mine own kind can say as much." She narrowed her eyes. "That knowledge is the burden I hold in my hand, child. Mine own belief is that it will destroy thee. The choice must needs be thine."
I stared at the gem for a long moment, forcing myself to breathe slowly. All the Ways. The ability to travel around the world without concern for geography. Knowledge like that could have won the war with the Red Court almost before it began. Whoever possessed that knowledge could regard laws with utter impunity, avoid retribution from mortal authorities or supernatural nations alike. Go anywhere. Escape from damned near anything. Gather more information than anyone else possibly could.
Hell's bells. That gleaming little gem was a subtle strength that had the potential to be as potent as any I had seen. Such power.
Such temptation.
I wondered if I'd be able to handle it. I am not a saint.
At the same time, I had never seen a tool so obviously intended to help a man Show Up for his little girl. No matter where she was, I could go to her. Go to her and get away clean.
Maggie.
I reached out and took the gem from my godmother's hand.

"Harry," Molly called from up in the living room. "I think they're waking up."
I grunted and lifted my pentacle necklace to examine it. The little pentagonal ruby had been quite obviously cut for this particular piece of jewelry. Or it had been before I'd been forced to use the necklace as a silver bullet. My little pentacle, the five-pointed star within a circle, had been warped by the extremes of stress I'd subjected it to. I'd been straightening it out with the set of jeweler's tools I used to update Little Chicago.
The jewel abruptly snapped into the center of the pentacle as if into a socket. I shook the necklace several times, and the gem stayed put. But there was no point in taking chances. I turned it over and smeared the whole back with a big blob of adhesive. It might not look pretty from the front after it had dried, but I was pressed for time.
"That'll do, pig," I muttered to myself. I looked up to Bob's shelf, where Mister was sprawling, using a couple of paperbacks for pillows while he amused himself dragging his claws through the mounded candle wax. I reached up to rub his ears with my fingertips, setting him to purring, and promised myself I would get Bob back soon: For the time being, he was, like the Swords, too valuable and too dangerous to leave unguarded. In Lea's bloodthirsty garden, they were probably safer than they had been in my apartment in the first place.
I left my mother's amulet and the glittering ruby sitting on my worktable so that the glue could dry, and padded up the stepladder.
