Since I am now rating books in two ways here is the key:
B: Pretty Dang Good
C: Okay I guess
D: Time Waster
F: Finish this?! No way!
Y: Youth or everyone. No bad content
G: Maybe some brief kissy stuff
Pg: Kissing/ brief swearing
Pg-13: Sexual content/ swearing
R: Very bold sexual content/ lots of F bombs
Hope that helps....
