Which Harry Potter novel contains the dedication to Jessica, Anne, and Di?

Harry Potter and the Deathly Hallows contains J.K. Rowling’s dedication to Jessica, Anne, and Di. It is the seventh and final novel in the original Harry Potter series.

The three names refer to Rowling’s daughter Jessica, her mother Anne, and her sister Di. Rowling’s mother died in 1990, before the Harry Potter books were published, and the loss influenced elements of her writing and personal history.

The dedication is unusually arranged across three pages, with the final dedication page ending in a single word. Harry Potter and the Deathly Hallows was published in the United Kingdom on 21 July 2007, concluding Harry’s main conflict with Lord Voldemort and resolving the series’ central mysteries.
