The Curious Magics Saga

"It was commonly accepted that judging a book by it's cover was just about the rudest and un-wisest thing you could do. But that's not going to stop you, is it? And that's something I've always respected about you. If the ideas of the trials and tribulations of a pair of wizards travelling through time and space do nothing for you, then you've most likely already put this book down. To those who remain, may I just take a moment to introduce Kiko and Kara. Kiko was a bookish, kind (but slightly bizarre) human girl with a razor-sharp intellect and Kara was the kind of Half-Elf to punch me in the face if she heard me say anything bad about her, so I won't be doing that. Both girls lived a life of magic and mystery on the thirteenth paralleled Earth, which was part of the Thirteenth parallel Universe; which is where this book is set."
