My Grandmother Asked Me to Tell You She's Sorry by Fredrick Backman

My Grandmother Asked Me to Tell You She's Sorry by Fredrik Backman is a novel that tells the story of seven-year-old Elsa, who is different than other kids and often picked on at school. 

Her best, and only, friend is her grandmother, seventy-seven years old and crazy—as in standing-on-the-balcony-firing-paintball-guns-at-strangers crazy. At night, Elsa takes refuge in her grandmother’s stories, in the Land-of-Almost-Awake and the Kingdom of Miamas, where everybody is different and nobody needs to be normal.

When Elsa’s grandmother dies and leaves behind a series of letters apologizing to people she has wronged, Elsa’s 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 new friends from her grandmother's world, including Wolfheart. The story is an odd one, but finishes nicely, and is about being different, having family, friends, and protectors.
