Junior gets an email from his sister. Where and how was she doing?

In chapter 13, Junior gets an email from his sister, Mary, dated November 16, 2006. The letter provides a point of view shift as Mary is able to speak for herself and add a different layer of legitimacy to the "absolutely true" portion of The Absolutely True Diary of a Part-Time Indian.
In her email, Mary explains that she is currently living in Montana with her husband. Her email is an overly optimistic one as she explains to her brother that dreams can come true and details how happy her life is. She gushes over her love for her husband, their new town, and her brother. She admits to having some trouble looking for a job and gives hints to homesickness as she describes the traditional Indian frybread on her honeymoon at Flathead Lake as being nearly as good as their grandmother's. Mary explains that the reservation (the Flathead reservation) is very large, as it is comprised of six or seven towns in Montana that are different in that they seem to have more white people than Indians.
Mary's short letter is extremely happy, but as the reader knows her fate, it can be read as one that masks her pain.
