* At the end of the book, after Anna wins her lawsuit, she indicates to her lawyer that she intends to go through with the transplant anyway. She's just fought a battle for, and been granted, the the right to choose, and she ''chooses'' to save her sister. Doubles as a TearJerker because it suggests that [[spoiler:if not for the accident, both Kate and Anna could have survived -- even though Kate seems to think otherwise.]]

* Brian taking his kid to the beach. Small but he’s spending the limited time he has with his kids rather then letting his kid rot in a hospital bed thinking it would make her betters. Double heartwarming is how he stands up to his wife [[spoiler: who is basically using one kid for spare parts.]] and just let’s her have her tantrum demanding to take their daughter back to the hospital. Triple heartwarming is how he doesn’t even lose his temper when talking to her he just tells her he’s done letting her have her way and he’s letting his kids be kids.

* In one blink-and-you'll-miss-it moment, Jesse tells his mother that he's been donating platelets to Kate too (since that only requires a blood type compatibility rather than the kind of precise genetic match needed for bone marrow and organ transplanting).

* At the end of the book, after Anna wins her lawsuit, she indicates to her lawyer that she intends to go through with the transplant anyway, the difference being that this time it's ''her'' choice.

* Kate herself is willing to give up her life so that Anna can live hers to the fullest. It's especially poignant in the book because it's flat-out stated that she doesn't ''want'' to die, she just doesn't want to keep living at Anna's expense.

* Doubling as a TearJerker, when [[spoiler: Anna dies]], her father uses an astronomy metaphor to explain how he feels. Sometimes two stars are wrapped up in each other's orbits, too close to distinguish or include anything else.
-->It's not until the smaller one goes out that you realize how brightly it really shone. And then, really, it's too late.
** It's doubly meaningful as Anna's real name is Andromeda. (Bryan picked it out)
