I finished reading True Colors by Kristin Hannah today - I finished it inside a week.  I read one of her books last year (Firefly Lane) and I remember feeling the same way about both books.  That she isn’t a great writer, has average character development, uses annoyingly cliche phrases throughout and yet she weaves together a saga that make her books unputtdownable. 

If you are looking for a ‘beach read’ then I would recommend her books.  It takes very little brain power to digest but you will enjoy them.
