The reviewer finds this book to be the best standalone in the series, appreciating its balance between middle-grade fare and darker themes. They highlight the expanded world and characters, particularly the introduction of Sirius Black and the Marauder's Map, as standout elements.
The reviewer enjoys this book the most among the Harry Potter series, particularly as a standalone story. They appreciate the balance it strikes between the lighter, more middle-grade tone of the first two books and the darker themes of the later installments. The expanded world and characters, especially the introduction of Sirius Black and the Marauder's Map, are highlighted as particularly engaging elements. The reviewer also notes that while they enjoyed the later books more as part of the overarching storyline, this book stands out for its self-contained narrative and memorable moments.
Quick quotes
Of all the books, most people say this one's their favorite. I believe a big reason why is it hits the sweet-spot between the middle-grade fare of the first two and the dark seriousness of the last four.
On the whole, I enjoyed the last four more, as serial installments of the "Voldemort is back" storyline.
But of the standalone books, I like this best.
