I Am Still Alive is a YA novel (which I didn't realize until I was well into it) about a girl who's lost everything and has to go live with her estranged father literally in the middle of the wilderness in Canada. There are no roads or cars... only a plane that shows up occasionally to get in and out.
Inheritance: A Memoir of Genealogy, Paternity, and Love by Dani Shapiro is a book about self discovery. When Shapiro, in her fifties, discovers that the father who raised her was not her biological father, she tail spins into an identity crisis. This is a story that delves deeply into identity, who we are and what makes us us.
