Keller teaches young readers (and frankly, older ones too) that "breakable" is not a flaw. It is a fact of life. Glass is breakable. Eggs are breakable. Human hearts are breakable. But that fragility doesn't make them worthless. It makes them precious.

The “science” in the title isn’t just about physics or botany; it’s Natalie’s way of trying to solve the unsolvable problem of her mother’s sadness.
