Query: This is a very shallow book, seems like written in a hurry

Can't say it is a good book, when it isn't. Lucifer's Hammer was MUCH BETTER, like if written by some other author. This one is pushing slowly, nothing really happens, you know it all ahead, only perhaps the end is a little fun, but it is not unexpected. It is all so very unfinished, a lot of stuff happens, but is left open, perhaps they tried to do too much in too little space. It could be twice as long but who the hell would read it then. With one word: BORING !
