Query: a boring novel

This book is about a man who travels back and forth in time to meet himself in various situations. It reaches a point where you the reader can predict what will happen in the scenes and that's never a good sign. Honestly there really isn't much more to it than that and it's easily apparent that it's a cliched plot if you are a well read science fiction reader. And that is never a good sign. Oh there are so many better time travel stories out there, in this readers opinion, (I've been reading sf for 30 years now! I read at least 10 sf novels a month). This is just not worth wasting your time on.Try the ever successful and enjoyable 'The Time Traveler's Wife' which features some real human pathos and excitement in the time travel tale.
