The ‘rules’ are: "Go to page 7 or 77 of your latest work. Read down to the seventh line and then post online the next seven lines or sentences. Then head off and tag seven more writers."
I decided to interpret "latest" as "latest published," so here's the appropriate passage from "Serkers and Sleep", currently up on Beneath Ceaseless Skies:
Thousands of heavily armed soldiers, destroyed in an afternoon by a man like a demon, moving too fast to see, strong enough to crush skulls with a fist -- I shuddered.
"Why does the early stage last only two days?" I asked.
"Sometimes three, and I don't know. The potential lines change abruptly. The muscles and bones no longer seem to draw power from the world, but the potential in the brain changes -- the lines twist."
"They're crazy," said Dipper, unable to stop herself.
Marmot stopped walking and pursed his lips.
And now I shall tag azahru, celestialgldfsh, enggirl, Ken Liu, heatheralbano, mmerriam, and theferrett.
