They’d like you to know that not all kids who can’t sit still are brats. Not all kids who refuse to sleep are troublemakers. And not all kids who scream at the top of their lungs are disobedient.

They’re kids. And they’re trying. And so are their parents.

My deepest appreciation to Kathy Regan and her staff at the Child Assessment Unit in Cambridge, Massachusetts. They tirelessly answered my questions, while allowing me to spend time on a real psychiatric ward. I could not have created my fictional psychiatric children’s ward, PECB of the Kirkland Medical Center, without the benefit of learning about their experiences and approaches. While I allowed the fictional PECB to use a progressive approach inspired by CAU’s impressive work, the center itself, its staff, and their actions are purely products of my (highly disturbed) imagination and bear no resemblance to the first-class operation run by Kathy and her staff at CAU.

For anyone who’d like more information on the CAU’s progressive approach, I recommend Opening Our Arms: Helping Troubled Kids Do Well, by Kathy Regan. I also recommend The Explosive Child, by Dr. Ross W. Greene, for a detailed look at the collaborative problem-solving (CPS) approach.

On the more mundane side of research, a happy shout-out to my favorite pharmacist, Margaret Charpentier, who once again helped me pick the perfect poison. It’s been a while since we’ve gotten to collaborate. I think the results are fun, as always.

Kill a Friend, Maim a Buddy: Congratulations to Audi Solis for being chosen as the sixth annual Lucky Stiff. I hope you enjoy your grand end. Sharing the fun across the Atlantic, Jo Rhodes won the Kill a Friend, Maim a Mate. According to Eleane Rhodes, it was the least I could do.

Under “Care and Feeding of Authors,” thank you to Michael Carr, whose pen functions more like a scalpel when editing a manuscript. I cried only for a little bit, and the book is better for it. My appreciation to my first readers, Kathleen, Barbara, and Diana, for doing an excellent job, as always, with the page proofs. And finally, the big guns—I couldn’t do this without Meg, Kate, and the support of my entire publishing team. Thank you for making the magic happen.

On the home front, my love to my patient husband and my not very patient but always adorable child.

Finally, this book is in memory of Michael Clemons, a good man, gone too soon. We miss you.
