Been reading these books for years and i have almost every single one. Almost a habit at this point, but now I'm just addicted to Nikki's life. I've kind of outgrown how dramatic and extra the book can be but thats just whats supposed to happen. Wonderful for young middle schoolers and elementary schoolers. High school might be pushing it a bit, but I feel like it can still be very enjoyable for a light hearted read.
