Really that is all I can tell you about The Book Thief without spoilers, though the book itself does give you various spoilers throughout. This is because the narrator is Death, and Death has little time for building suspense and mystery.
The unique narrator is just one of the things that makes this book memorable. Another would be the author's choice to set this book inside Germany during WWII. There's also the writing, and the fantastic characters Zusak brings to life.
All of these things take a while to culminate together and make you truly care, but once you do, man, you do. Which is what makes the ending so gut-wrenching.
In the end I just wanted to let you know that all of those things you've heard about The Book Thief over the years are 100% true. Yep, it'll make you laugh and cry (or sob). Yep, it'll have you pondering the frailty of life and the bonds we form. Yep, you should definitely ignore the thickness of it and just read it.
Plot: Gorgeously woven and intense.
Characters: Fantastic. I felt like I was living on Himmel Street myself.
Writing: See above.
Ending: Writing Marcus Zusak some hate mail.
Content warning: There are, of course, mentions of the brutality of the period. However, there aren't as many as there could have been. There's some swearing, but it's mostly in German. This one is probably better suited for an older teen, though.
Don't you EVER interrupt me while I'm reading a book/crying.
Though I took my sweet time getting through The Book Thief, it still captured my heart fully. Days after reading it, I'm still thinking about it.
I received my copy for free from my library.
