I was about that age when I first read the Fowl books, and they were some of my favorites! There were a few concepts that I didn’t fully understand at the time (e.g., I wasn’t sure what the Russian mafia was when they discussed it in book 2), but overall there’s nothing horribly traumatizing for a child in there. Your kid will be fine!

Not to detract from the tragedy of her death, but the Steven Wilson album based on this story is an absolute masterpiece.
