From The Grey House, Book Two, Inside the Grey House:
Natalia threw her head back as the shudders increased and her body heaved one final time. Acid, blood and other liquids came boiling up her throat and out her mouth. The large glob sank to the bottom of the tub and started to mix with the water. Natalia sank to her knees. Consciousness seeped in as she was helped to the seat. She felt cool glass touch her lips and water trickled down the corners of her mouth until she sucked it in and started drinking. She was only given a swallow or two before the glass was pulled away. She felt a hand take hers and the glass was placed in it. She dropped the glass a second later.
