With Voldemort in control of the Ministry of Magic and Hogwarts no longer safe, Harry, Ron and Hermione abandon school and go on the run, tasked with finding and destroying the remaining Horcruxes — the objects in which Voldemort has hidden fragments of his soul to escape death. The hunt takes them to the Ministry, to Gringotts, and finally back to Hogwarts, and it is gruelling: the three are isolated, hunted, and fractured by the pressure while the Wizarding World collapses around them.
Threading through the quest is a second mystery — the legend of the Deathly Hallows, three objects said to make their possessor the master of death. Voldemort is chasing them too, and what Harry decides to do about them shapes the confrontation both are moving toward.
The seventh and final Harry Potter novel resolves the series' major threads in a battle at Hogwarts, and closes with an epilogue set nineteen years later. It is, above all, a book about death — about facing it, and about what a life given in love can accomplish that no amount of power can undo.
