I loved Ruby & The Stone Age Diet, it was wild and off the wall. I didn't enjoy Lux the Poet as much but it was still a really unusual read. There were just so many characters to follow, some were interesting others were boring and it lost my interest at times. He's still an amazing author with a very different style. I would recommend reading them both though, I just liked the top one more. I'm planning on reading more by him too cause Martin Millar creates such a realistic and sometimes insane world for his kooky characters, that it's hard to go back to reading regular styled books.
