I do like Gaiman's books. I haven't read The Ocean... yet, but I have it both as a paper book and as an e-book, and will definitely read it. I like Neverwhere a lot, and his short stories, too... I think my favourite among his books is Stardust.
Have to admit I lost interest in Game of Thrones after two books. They were gripping while I read them, but I forgot the plot very quickly and so never got back to reading them. GRRM is a bit too fond of details for my taste.
