Harry Potter and the Half-Blood Prince (2009)

Now, not only the world of wizards, but also the world of Muggles feels the ever-increasing power of Voldemort, and Hogwarts can no longer be called a safe haven, as it used to be. Harry suspects there is some danger lurking within the castle itself, but Dumbledore is more focused on getting him ready for the final showdown, which he knows is just around the corner. Together they are trying to unravel the secret of Voldemort's immortality, and for this, Dumbledore invites his old friend and colleague, Professor Horace Slughorn, who loves to throw parties for the elite and is proud of his extensive connections in high circles. But this bon vivant does not suspect that it is from him that Dumbledore hopes to get the most important information about Horcruxes.

Meanwhile, students are attacked by a variety of enemies, and teenage emotions are whipping over the edge. Harry begins to realize that he is becoming more and more partial to Ginny, however, and Dean Thomas too. And Lavender Brown got it into her head that Ron was the one she was waiting for, but she didn't take into account the magical effect of Romilda Vane's chocolates! And finally, Hermione burns with burning jealousy, but tries not to show her feelings. As the romance blossoms, only one student is left behind. He is determined to leave his mark, the dark mark. Love is in the air, but trouble lies ahead, and Hogwarts may never be the same again.
