I know I'm a rare person, a trained scientist who writes fiction, because so few contemporary novelists engage with science.

I've never gotten over high school, to the extent that I'm still a little surprised that my friends want to hang out with me.

No matter what kind of night you're having, morning always wins.

We came from Bethlehem, Georgia bearing Betty Crocker cake mixes into the jungle.

Hallie and I... were all there was. The image in the mirror that proves you are still here. We had exactly one sister apiece. We grew up knowing the simple arithmetic of scarcity: A sister is more precious than an eye.

Our holiday food splurge was a small crate of tangerines, which we found ridiculously thrilling after an eight-month abstinence from citrus.... Lily hugged each one to her chest before undressing it as gently as a doll. Watching her do that as she sat cross-legged on the floor one morning in pink pajamas, with bliss lighting her cheeks, I thought: Lucky is the world, to receive this grateful child. Value is not made of money, but a tender balance of expectation and longing.

When I look out the window, I exhale a prayer of thanks for the color green, for my children's safety, for the simple acts of faith like planting a garden that helped see us through another spring, another summer. And I inhale some kind of promise to protect my kids' hopes and good intentions we began with in this country. Freedom of speech, the protection of diversity - these are the most important ingredients of American civil life and my own survival. If I ever took them for granted, I don't know.
