I bought the first and second book together at a book club. The second book had just come out. It was a given that i would get the next in the series, as i fell in love with the genre and characters. But the one where i fully fell in love was book 5. That book made it a favourite series. The twist ending, the writing and i clearly remember where i was when i finished that book. It is one of my favourite childhood memories. And ill never forget it.
