The book Tornado Warning is about a woman who describes her life as part of an abusive relationship as a teenager and its effect on her life as an adult.

Elin Stebbins Waldal published her teenage diary to bring awareness to teen dating violence. 

I should be dead, I think—but I am not. Why have I not told my story? There was a false start in my early twenties when I gave voice to my teenage self by writing about it.

Teenage Elin fell under the spell of an older boy when she moved into a friend’s house away from her family.  In the book, she shares her diary entries as well as comments from her adult self. 

And that’s when it crept into me…he really can’t kill me…well, he could, but that’s not what I mean. What I mean is, he actually already has, because he’s killed my spirit.

Her purpose is to show how she did not see the warning signs early in the relationship, and she hopes to get a dialog going on teen dating violence.
