My English Book

Hiho, now I'm reading my first english book! It's called boom! by Mark Haddon (special thank's to Dominik for borrowing me the book :D). When I first saw the cover I thougt that there will with space, other Galaxies, UFO's or Aliens. I thougt it would be funny tho read such a book, because Science Fiction Stories are really cool. What do you think about this book?
