Book 135: Harry Potter and the Half-Blood Prince

Harry Potter and the Half-Blood Prince by Rowling is the sixth installment in the series.  Voldemort's power is on the rise and even the muggles are noticing the problems.  Harry returns to Hogwarts as Quidditch captain and has private lessons with Dumbledore to look forward to.  His options abilities improve by leaps and bounds when he borrows an old textbook full of hand-written notes in the margins, and he spends a lot of time trying to figure out what task Voldemort has set Malfoy to accomplish at Hogwarts.  5 stars
