This month's book is The One Hundred Years of Lenni and Margot by Marianne Cronin.
Determined to leave a mark on the world even though they are in the hospital and their days are dwindling, unlikely friends, seventeen-year-old Lenni and eighty-three-year-old Margot, devise a plan to create one hundred paintings showcasing the stories of the century they have lived. Seventeen-year-old Lenni Pettersson has been told she's dying, but still has plenty of living to do. She lives on the Terminal Ward at the Glasgow Princess Royal Hospital. In their arts and crafts class she meets Margot, an 83-year-old, purple-pajama-wearing, fruitcake-eating rebel. Their friendship blooms, and though their days are dwindling both are determined to leave their mark on the world. With the help of Lenni's doting palliative care nurse and Father Arthur, the hospital's patient chaplain, Lenni and Margot devise a plan to create one hundred paintings showcasing the stories of the century they have lived: stories of love and loss, of courage and kindness, of unexpected tenderness and pure joy. -- adapted from jacket
