What book have you attempted to read several times but have never been able to finish?

This has never actually happened to me before. Some books take me a long time to get into, but when I finally do I find that it was worth the effort.

Although I never attempted to actually read the entire book - I have read many passages, and parts of the Bible.

The Hunger Games(the first book).I tried to get into it,but just couldn't.I think I got up to chapter 3 or 4.I have seen all the movies,but just can't get into the books.

Spirit of the Border.
I amor that book, but I haven't been able to finish.
