I'm big on light mysteries (not the ones with graphic descriptions of violence). I've been reading my way through the Daisy Dalrymple series by Carola Dunn, about a 1920s English aristocrat who eventually marries a Scotland Yard detective.
I finally hit #1 on the library waiting list for Sue Grafton's latest, U Is for Undertow, and I'm reading that now.
The most recent good non-fiction I've read:
The Cure by Geeta Anand, true story about how a father started his own biotech company to try to save his children's lives from the genetic disease, Pompe Syndrome.
The Checklist Manifesto: How to Do Things Right by Atul Gawande, MD
Growing Up Bin Laden by his wife and 4th son, along with Jean Sasson. I read this about a month ago. Enthralling, but sad. Ultimately, he didn't treat his family any better then the unwashed, uneducated terrorists-in-training in his camps.
I know I read some worthwhile fiction lately, just can't think what...
