3. Station Eleven by Emily St. John Mandel. I couldn't put this book down, and I'll be recommending (and loaning) it to everyone I know. The story of a traveling symphony and theater company in the years after most of the world died in a flu pandemic, this book is so richly-imagined I felt like I lived through these events.
5. Freezer meals. I'm still learning how to get everything done while carrying a baby around most of the day, so I love being able to make meals ahead of time and dump them in the crock pot when I need them. Some of my favorites here and here.
