For this book, I found the mysteries aren't really well thought out or clever anymore. And to add something, now the relationship between Friday and Ian is just 'oh, I love you' and 'kiss, kiss'. I liked it better when they were NOT together. The enemies to lovers would have been cool if they didn't just be lovey, lovey with an 'eh' plot. I think to fix this, you could make them break up, and then get back together, but I don't know
Otherwise, love this book series! I read them over the summer holidays years ago, since my sister owned the first 8 books, and ever since I've read them over and over again. I fell in love with Friday's personality and nerdy comments, let alone how sisterly and funny Melanie seems, and don't get me started on Ian. It's written well with small details that tie together the whole mystery, making it seem well thought out. Definitely my favorite book series!
