I'm a great Elvis fan and thought to myself "How can Elvis be in a Sci-fi book?", but it turns out he can! And lots of other persons and creatures can too. I love the parts with Elvis, of course, but also, the book is very, very well written, the plot is brillint, and the science in it is for real. I double checked a lot of the facts, and found them to be accurate, so maybe time travelling is possible after all.
I would have given it five stars but for the fact that I will have to wait for the sequel in order to hopefully read more about one or two of the book characters. The book is thoroughly enjoyable, funny, clever and very hard to put down once you've started reading. I would recommend it for teens (15+) and definitely adults.
Well... The book is quite well written, and still, after reading the forst 30 pages, I still don't know where it is going to take me. The first hint of conflict appears on page 8, and then, after another 8 or 10 pages, comes a follow-up. Somehow, despite quite a few things happening, nothing much seems to happen. Maybe I just wasn't in the right mood for reading this particular type of book, so I'll most likely have a go at it again in the near future.
