I read a lot of books about time travel and not all of them were good so I was a little apprehensive about reading Timebound as I did not think it would be an original story. I must say I am very glad I read the book because it is extremely well written, has very engaging and well developed characters. The time travel aspect is original, well explained and is very logical which makes it easy to understand and follow the story. Some reviewers pointed out that the story was confusing, but I thought the confusing bits were part of the story and not the result of the bad writing as these were the parts that the main character Kate did not understand either. I think they will be explained in the following books.The only disappointing bit is that we have to wait till October 2014 for the next book.
