Nell closed up the book. This was too upsetting to think about just now. 
She had been collecting those keys for most of her life. The first she'd taken 
from King Magpie just after she and Harv had arrived at Dovetail. She had 
picked up the other ten one at a time during the years since then. She had done 
this by traveling to the lands of the Faery Kings and Queens who owned those 
keys and using the tricks she had learned from her Night Friends. Each key had 
come to her in a different way.
