Most days, Magda is fine. She has her routines. She has her anxious therapy patients, who depend on her to cure their bad habits. She has her longtime colleagues, whose playful bickering she mediates. She's mourning the recent loss of her best friend, Sara, but has brokered a tentative truce with Sara's prickly widower as she helps him sort through the last of Sara's possessions. She's fine.

But in going through Sara's old journal, Magda discovers her friend's last directive: plans for a road trip they would take together in celebration of Magda's upcoming seventieth birthday. So, with Sara's urn in tow, Magda decides to hit the road, crossing the country and encountering a cast of memorable characters--including her sister, from whom she's been keeping secrets. Along the way she stumbles upon a jazz funeral in New Orleans and a hilarious women's retreat meant to "unleash one's divine feminine energy" in Texas, and meets a woman who challenges her conceptions of herself--and the hidden truths about her friendship with Sara.

As the trip shakes up her careful routines, Magda finally faces longings she locked away years ago and confronts questions about her sexuality and identity she thought she had long put to rest. And as she soon learns, it's never too late to start your next journey.
