The actress wrote Bliss with pal Michaela Blaney and admits it's a little racy.

She explains, "It's very much not the Pretty Little Liars demographic... It's a little bit older so I'm suggesting that people be 18 and older to read it. It's fun. It's loosely based on my life and my friend's life on getting to where we are."

Bliss will hit book stores in October (15).
