As this story largely takes place in the Bay Area, I didn’t think I had used the word ‘horse’. Turns out, I did.
From The Grey House:
She was sitting in the middle seat of a horseshoe booth at the back of The Red Thread, flanked by two Slayers on either side. Zechariah was to her right, with Marshal beside him. Miguel was to her left with Dean beside him. They were here to count the bodies. It was the middle of the week; there were fewer humans than usual, but there seemed to be more Hellspawn. The Slayers were betting on how many would die.
