From Protector of the Grey House:
It took her two months to decide whom to tell about the demons Edwin summoned. It took three months to convince Ashley to meet her, and another month to plot the best place to meet. Natalia had been spying on the place for the past two weeks, finding as many ways out as possible. There were two conventional ways: front entrance and back kitchen door. The two walls facing the street were beautiful picture windows. She was pretty sure the windows were regular glass and could be busted with a diner chair or Slayer if necessary. She also noticed who were regulars and who were not. Half of the people frequenting the small café today were not regulars. She was ready for the battle she hoped she wouldn’t have to fight.
