Query: POORLY WRITTEN TITANIC BOOK

THIS IS BY FAR ONE OF THE WORST PIECES OF FICTION I HAVE EVER READ. SOME CHARACTERS APPEAR AND FLOAT ABOUT THE BOOK WITHOUT A PURPOSE. OTHER CHARACTERS APPEAR AND DISAPPEAR TO THE POINT THEY DO NOT EXIST. MOTIVATIONS ARE UNCLEAR OR VAGUE AT BEST. I WISH THE AUTHOR HAD RESEARCHED THE STORY BETTER.
