Again I lunged. Again—again—again....

My shoulders were bruised now, my whole body aching. It was all I could do to stumble back for still another try.

Only then, suddenly, light spilled in upon us as the door swung open.

Unbelieving, I rocked back. Celeste Stelpa gave a choked, incoherent cry.

I held my breath and tensed my belly, waiting to see what form our foe would take.

Nothing happened.

I looked round at Celeste, and she at me.

Still nothing.

For an instant I stood rigid. Then, tight-lipped, I took a quick, cat-footed step in the direction of the open door.
