  "description": "\" Uviděl je okamžitě, vznášelo se na obloze nad školou: zářivě zelená lebka s hadím jazykem, znamení, které za sebou zanechávali smrtijedi pokaždé, když někam pronikli... pokaždé, když vraždili...\" Moc Lorda Voldemorta stále roste a smrtijedi působí spoušť ve světě mudlů i kouzelníků. Když Harry Potter objeví starou učebnici lektvarů patřící tajemnému princi dvojí krve, spoléhá na její kouzla i přes varování svých kamarádů. Profesor Brumbál poodhaluje Voldemortovu minulost a s Harryho pomocí se snaží odkrýt tajemství jeho nesmrtelnosti. Jenže zlo se dere k moci stále silněji, neštěstí se blíží a Bradavice už nikdy nebudou jako dřív.",
