QUICK SYNOPSIS: Voldemort is tightening his grip on both the Muggle and wizarding worlds and Hogwarts is no longer the safe haven it once was. Harry suspects that dangers may even lie within the castle, but Dumbledore is more intent upon preparing him for the final battle that he knows is fast approaching. Together they work to find the key to unlock Voldemort's defenses and, to this end, Dumbledore recruits his old friend and colleague, the well-connected and unsuspecting bon vivant Professor Horace Slughorn, whom he believes holds crucial information.
Meanwhile, the students are under attack from a very different adversary as teenage hormones rage across the ramparts. Harry finds himself more and more drawn to Ginny, but so is Dean Thomas and Lavender Brown has decided that Ron is the one for her, only she hadn't counted on Romilda Vane's chocolates! Then there's Hermione, simpering with jealously but determined not to show her feelings. As romance blossoms, one student remains aloof. He is determined to make his mark, albeit a dark one. Love is in the air, but tragedy lies ahead and Hogwarts may never be the same again. And yet, as in all wars, life goes on. Sixth-year students learn to apparate and lose a few eyebrows in the process.
The Weasley twins expand their business. Teenagers flirt and fight and fall in love. Classes are never straightforward, though Harry receives some extraordinary help from the mysterious Half-Blood Prince. So it's the home front that takes center stage in the multilayered sixth installment of the story of Harry Potter. Here at Hogwarts, Harry will search for the full and complex story of the boy who became Lord Voldemort and thereby find what may be his only vulnerability.
