<P> Ginny is a first - year in Harry Potter and the Chamber of Secrets, in which she develops a crush on Harry and is sorted into Gryffindor . During the climax of the story, it is revealed that she opened the Chamber of Secrets, and is attacking Muggle - born students while being possessed by Tom Riddle's (Lord Voldemort's) old school diary . Lucius Malfoy had slipped the diary into Ginny's cauldron in Flourish and Blotts prior to the term . She has little involvement in Prisoner of Azkaban, though she is studying at Hogwarts throughout the book . In Goblet of Fire, her role was larger as she attends the Quidditch World Cup and the Yule Ball with Neville Longbottom and can be seen in background appearances . </P> <P> In Order of the Phoenix, Ginny has "given up on Harry months ago" (though this is merely a ruse as Hermione previously advised her to pretend to not be as interested in Harry and go out with a few other boys so Harry would eventually notice her), and has a boyfriend, Michael Corner, whom she met at the Yule Ball . When Umbridge punishes Harry with a "lifetime" Quidditch ban, Ginny replaces him as Gryffindor Seeker . She joins Dumbledore's Army and is one of five members who accompany Harry in his attempt to rescue Sirius Black from the Department of Mysteries . During the last part of the book, Ginny breaks up with Michael due to his sulking over Ravenclaw losing the Quidditch Cup final to Gryffindor, and replaces him with Dean Thomas . Towards the end of this book Ginny participates in the battle inside the Ministry of Magic, but is forced to withdraw from the action due to a broken left ankle . </P> <P> In Half - Blood Prince, after she casts the Bat - Bogey Hex on Zacharias Smith, Professor Slughorn respects her magical abilities enough to invite her to join his "Slug Club". Ginny becomes a permanent member of the Gryffindor Quidditch team as Chaser, and substitutes for Harry as Seeker when Snape puts him in detention during the Quidditch Cup final . After witnessing Ginny kissing Dean in an empty corridor, Harry has an angry internal reaction . This reaction surprises him and upon reflection, he realises his attraction to Ginny . Since Ron vocally objects to Dean going out with his sister, Harry fears his reaction would be the same with him . Ginny's relationship with Dean ends altogether in April following an accidental nudge from Harry under the effects of Felix Felicis, which Ginny interprets as Dean unnecessarily trying to help her through the portrait hole . Ginny and Harry share their first kiss after Gryffindor again wins the Quidditch Cup over Ravenclaw, thus initiating their relationship . After Dumbledore's death, however, Harry decides to end their relationship as he fears his love for Ginny would place her in danger . </P> <P> Propelled by the revelation that Harry, Ron, and Hermione are leaving to seek the remaining Horcruxes in Deathly Hallows, Ginny kisses Harry in her bedroom, and they realise that they both still have intense feelings for each other . She returns to Hogwarts for her sixth year, where she works with Neville and Luna on reuniting Dumbledore's Army . As Ron is on the run with Harry and Hermione, Ginny is forced to go into hiding with her family . Though underage, she takes part in the Battle of Hogwarts despite her mother's and Harry's disapproval . After Harry's supposed death, she, Hermione, and Luna take on Bellatrix Lestrange, who nearly strikes Ginny with a Killing Curse, infuriating Molly Weasley to the point of intervening and slaying Bellatrix herself . </P>
