Elsa is seven years old and different. Her grandmother is seventy-seven years old and crazy as in standing-on-the-balcony-firing-paintball-guns-at-strangers crazy. When Elsa's grandmother dies and leaves behind a series of letters apologizing to people she has wronged, Elsa's greatest adventure begins. Her grandmother's instructions lead her to an apartment building full of drunks, monsters, attack dogs, and old crones but also to the truth about fairy tales and kingdoms and a grandmother like no other.
