A lifelong resident of the Wilsburough Lake, and the older sister of Julienne “Julie” Keller. Both of the Keller sisters are friends with Rosemary Graves, and have been for many years. Madison in particular has been very worried about her, but hasn’t been able to reach out due to her own complications. Roughly a year before the events of the story Madison was diagnosed with a brain tumor and has less than 5 years to live, unless a miracle occurs.
She has spent her recent days traveling and spending time with loved ones. She wants to visit Rosemary and has tried many times in recent days but the latter seems to lack interest. Madison’s sister Julienne hasn’t adjusted to her sister’s condition, and won’t admit to herself that she is sick. Madison has been the topic for her sister’s recent poems.
Madison is kind and optimistic, and always has a smile on her face. She values the outdoors more than anything else, and loves her sister more than anything
