In Winona writer Marjorie Dorner's new novel "Seasons of Sun and Rain", a group of women-friends annual vacation together on Lake Superior's North Shore is overshadowed by shattering news. One of their number is suffering from "Early on-set Alzheimers." The women have been friends since college, sharing each others joys and sorrows as they have had families, and watched their children become adults. Dorner told Minnesota Public Radio's Euan Kerr the story is based on experiences she's had with her own friends. The central shocking secret in the novel...is fiction. Dorner says one of the women is about to get a huge test... she's been asked to promise she'll help her sick friend commit suicide at some time in the future.
