On my list -- I just purchased Lab Girl by Hope Jahren. Even though I spent years researching THE STORY OF SEEDS and spending time with botanists and other seed scientists, the subject will stay with me forever. And this book looks beautiful.
Following that theme - I'd love to read Elizabeth Gilbert's Signature of All Things. These three would make a great trilogy!
On the kid lit front:
I also downloaded the audio book of The War That Saved My Life by Kimberly Brusker Bradley. This book has been on my TO READ list since it came out. I am so happy to have the time now to listen to it.
