Book Suggestion on theme of the Holocaust for an 11 yo boy

[Tillyboo]

Hi, my almost 11 year old nephew showed an interest in my Geneology work as some of our family were Dutch Jews and many many of them perished in the camps.

He has an interest in what the camps looked like, what life was like etc. so I thought I'd try and find him a novel or maybe a factual book about this subject.

I've heard 'The Boy In The Striped Pyjamas' is a bit dark and scary. So, any other recommendations ?
Would 'The Diary of Anne Frank' be interetsing for a boy ?

I don't want to give him nightmares or scare him, even though he wanted to see graphic images.

Thanks

Check it out for yourself first though as been a long time since I read it so I can't say for sure if suitable for an 11-year-old

WRT films, I remember watching 'The Hiding Place' about Corrie Ten Boom's experiences in the camps, when I was probably about that age. Don't think I can have been much older.

I liked Mischling Second Degree.

Yes Mischling Second Degree

What about Hitler's Canary by Sandi Toksvig - based loosely on her family's experiences of WW2 in Denmark. My nephew loved it.
I read When Hitler Stole Pink Rabbit, and had the Puffin version with the dark jacket and pink rabbit on it. Decades later I met the author Judith Kerr (also of Tiger Who Came to Tea & Mog fame) at a book festival and couldn't think of anything coherent to say beyond how much I loved her book!

One other I haven't seen suggested on this list is The Upstairs Room by Johanna Reiss. It's about 2 sisters in hiding in the Netherlands so not about the camps but about the experience of the holocaust, might work well given your family was Dutch.
