My 7 year old gives this 4.5 stars, it's probably more like 3.5 for me. I read this aloud to him, and while it's very well researched and well written and contains tons of useful and interesting photographs, it's REALLY sad. There is lot of discussion of death (of children in particular) and funeral services, and unclaimed bodies; it's probably at least a third of the book which yes, I understand this is a book about a tragedy where 844 people died, most of whom were women and children, it was just a lot for me as a read-aloud. My son seemed fine, actually, but I kept having to stop reading it and collect myself. We've read a lot of books about shipwrecks/maritime tragedies together, but this one was by far the most upsetting.
I was surprised how few people know about this, even here in Chicago. It definitely deserves more attention than it gets, but as the author points out, most of the victims were poor immigrants, unlike the rich and famous passengers on the Titanic, which is probably (and unfortunately) a major contributing factor. The nurse who seemed to be coordinating most of the medical triage definitely deserves more recognition, she sounds like an incredible woman. Absolutely insane to think they crammed 2500 people onto this thing; 2500 was the passenger capacity of the freaking Titanic. Apparently there's a plaque at the site of the disaster, we're going to go check it out when the weather is nicer.
Anyway, this was super informative but just be aware that it's not a fun read.
