Madilyn never really understood people. Not as much as animals. When four siblings show up at her house to hide from the war and find her talking to a horse, her life changes forever.
Edmund and Rosalyn are neighbours, and she is a good friend of the Pevensie family. Lucy is like her little sister, and Peter and Susan like the older siblings she never had. Edmund was difficult, for as long as Rosalyn could remember they had been good friends, but after the Edmund turned 11 he started acting different and more distant towards her.
