I didn't like the ending, and therefore, the whole book. That's why I didn't post about it soon. Dumbledore died, Snape killed him, he's still a Death Eater and shockingly, he's the Half-Blood Prince! While going through the book, I thought that the Half-Blood Prince was Lord Voldemort until that "Flight of the Prince" chapter. Voldemort's childhood life was like the highlight of the book along with the Half-Blood Prince's Advanced Potions book. It was shown that Voldemort had a witch for a mother, who is a Gaunt, a family descendant of Slytherin. However, his father was a muggle named Tom Riddle, who left the witch pregnant with their son, who would soon be the Dark Lord. So Voldemort was half-blood, which led me to thinking he's the Prince. So much for juxtaposing...
The book was dreadful, but I thought that it still proved J.K. Rowling's imaginative prowess. The Unbreakable Vow and especially the Horcrux were unbelievable magic. Now I understand why and how Voldemort seems immortal. It's a hair-raising concept of a wizard having to kill so he can "tear" a part of his soul and store it in an object, which would be his Horcrux. So in case the wizard dies, his Horcrux, which contains his "torn soul," can bring him back to life.
What Voldemort did was to tear his soul in seven (!) parts because he thought that the number was lucky. So he made six Horcruxes! One part of his soul remained in his body, which was now dead. That's why he's after his Horcruxes now. Dumbledore presupposed that the Horcruxes were hidden and heavily guarded with magic. In the book, one of his hands was charred while destroying a Horcrux, which was the ring of Slytherin. Neat, isn't it?
Have to stop here now. Got to study for Philosophy. Can't wait for the seventh book...
