My Adopted Father Blasted Us In A "memoir," Would Love Advice

(also posted in r/legal)

So long story short, this guy adopted my siblings and I several year back. Those of us 18yrs and older are estranged from him for a bunch of reasons.

He recently wrote and self-published a "memoir" about the abuse my siblings and I went through as children. I say "memoir" in quotes because our abuse was not witnessed by him. This thing he published has pictures of my siblings and I as children, recounts loads of the abuse we went through, lists the town we lived in, didn't alter our first names (but changed last names), etc.

Aside from various lies and typos, the most harrowing part of the "memoir" is how he puts everyone on blast. We were minors and victims of abuse, we've changed our names and moved multiple times to ensure our safety and he drops this bomb anyway.

Should also be mentioned that he did this out of the country. (I'm in the US)

Do I have any legal recourse here? Is there anything I can do?
