[Suzerain of Sheol]

I've never read Harry Potter (despite having been in the target age demographic when it was released) but I'd classify it as Children's Literature. The only mark against it I can think of off the top of my head is how long it is. "Literature" tends to favor concision, though being a fan of certain Big Fat Fantasy series, I tend to not agree.

And quote, an excerpt from Shelly's When the Lamp is Shattered.

When the lamp is shattered,
The light in the dust lies dead;
When the cloud is scattered,
The rainbow's glory is shed;
When the lute is broken,
Sweet tones are remembered not;
When the lips have spoken,
Loved accents are soon forgot.
