My impression is that it must be a bigger thing. Based on what we've seen, the language seems strong, but she has the name from Death in the bigger picture, right?

Yeah, I agree... especially because Death does so much ominous foreshadowing. I already felt like I missed something in the stuff you're reading now that is big foreshadowing for what I'M reading right now. I should maybe go back and read that stuff again! Anyway. Foreshadowing.

I like BOTH of her new 'parents' so much, and for different reasons. I mean, Rosa is HORRIFYING in some ways, but her caring is also so obvious, that all her slapping and cursing and terrible behavior sort of pales behind it.

I figured it wouldn't have a happy ending, but I'm awfully intrigued by the stuff Death gives away. You definitely get pieces and parts of BIG STUFF to happen later throughout the earliest parts of the book, which either means the journey to get there is way more important than the actual ending OR that what you think is big isn't nearly as big as you think and there is BIGGER stuff.
