Christmas Tree by Julie Salamon
"The Christmas Tree is the tale of a little girl named Anna, who is orphaned and sent to live in a convent. The lonely girl befriends, as only a child can, a tiny fir tree. Anna and Tree, as she calls him, grow up together, unlocking the secrets of friendship and sharing the wonders of nature. It is this same profound appreciation and love of nature that the grown-up Anna, now Sister Anthony, passes on to her students.
When Tree is threatened by a winter storm, Sister Anthony, by now an old woman, decides to give up her dearest friend, allowing him to become the most enjoyed and famous tree of all: the tree at Rockefeller Center in New York City.
A perennial holiday favorite, The Christmas Tree is about learning to love and, ultimately, being able to share that love with others."
