Saga was a good story --I liked the idea of an interracial/species romance (reminded me of some Star Wars EU characters actually) and having Hazel as the narrator was a neat way to tell the story. I enjoyed how you got bits of back story and information as you read. The illustrator also has a nice style that I enjoyed. 
 I wasn't crazy about the sexual content depicted (though as a former art student, they were mostly tastefully posed) and the f-bombs, but I know a lot of people (especially those my age) are more comfortable with that type of language than I am. I personally think the story is just as strong without those types of content ... it didn't really need it. Because of this, I'd recommend this to adults only or to teens that are comfortable with R-Rated content. 
 If I decide to continue reading this series, it will be via the public library ...
