Elana K. Arnold: Hello. My name is Elana K. Arnold. When I was married I took my husband's last name Arnold because I knew we were gonna have kids someday, and I wanted us all to share one name. But I didn't wanna get rid of my original name Kuczynski, and so I took it as a middle name. So my full name is Elana Kuczynski Arnold. But that seemed awfully long to put on the spine of a book. So Elana K. Arnold it is.
