1) This book was completely different from what I expected, and yet still that.

2) The quotes on the cover say "one of the best twists in years", so my expectations were pretty high, but the book delivered. They also say "hilarious and heartbreaking", but I was having trouble finding the hilarious part.

3) There's really no good way to talk about this book without spoiling the whole thing, but wow. Just wow. Also, prepare for lots of discussions of animal experiments and animal cruelty.

4) This is a heartbreaking, complex and compelling story about two parents and three siblings, one family.

5) I was going to rate it 4 stars because it got kind of boring in the second half, but then the part taking place in 2012 absolutely killed me and it was beautiful.
