Kerstin Simonsson was the wife of Nils Simonsson, and together with him she guarded the portal to Gothia inside their rackety old antiquarian bookshop. Alvan thought of her as a grandmother-figure.
She was described as wrinkly and a bit tubby. Alvan wouldn't know but she's rather proud over having most of her teeth intact at her age - only one has been replaced with a gold tooth.
- Kerstin Simonsson is based on my maternal grandmother, though instead of drinking warm water she drinks chamomile tea. Alvan, like me, is of the opinion that herbal teas taste like grass. Dry grass.
