Query: A Disapointing Sequel

Although this sequel was eagerly awaited, it did not live up to its expectations. 'The Ocean Within" chronicled real human emotion, but Tides existed merely to point out that families break up. Caldwell failed to portray her characters as realistically as in the prequel, and was often sidetracked by her theme of environmental conservation. All of this detracted from the substance of the book. However, I'm sure we can expect better works from this author in the future.
