What's a book you constantly re-read?

Mine would have to be The 10th Kingdom. It's the whole concept of all the fairytales knowing each other and live amongst one another. I find it such a great story.

10th Kingdom sounds interesting, I will have to give it a read.

Princess diaries 9 (to the nines). I literally have no idea why but i keep going back to it haha. I've also wanted to re read p.s i still love you a lot since ive read it though:))

Its a series but i would have to say the Serafina series is what i read over and over again
