Ahhhh!! I love Meg Cabot! I've been working my way through like... every single one of her books. I'm halfway through the mediator series right now.. but I think the heather wells series was my favorite... what about you? :)
Have you tried the House of Night books? I think you might like 'em based on some of the other stuff you listed you liked.
Anyhow! Before I get super distracted on a book nerd tangent, I just wanted to drop by to officially welcome you to wattpad! :) I'm one of the wp volunteers so if you've got any questions to get you started, feel free to send me a message and I'll do what I can! Just here to help :)
Hope you're having an awesome night!
