Quick Verdict
The Fly Away novel is a worthy, emotionally rich follow-up to Firefly Lane that rewards readers who connected with Tully and Kate the first time around. It's not a light book—by the final chapters I had to set it down twice just to breathe. If you loved the original, this sequel deepens everything. If you haven't read Firefly Lane yet, start there first. I'd give it 4.2 out of 5 stars – it falls just short of perfection because some middle sections drag, but the ending lands hard in the best way.
What Is Fly Away About?
I unboxed my copy on a grey Thursday afternoon and told myself I'd just read the first chapter. Four hours later the sun had set and I was halfway through. That's the thing about Kristin Hannah's writing—it pulls you sideways into these women's lives before you realize what's happening.

Fly Away picks up the story roughly fifteen years after Firefly Lane ended. Tully Hart is a media mogul, rich and famous and utterly alone. On the outside she has everything. Inside, she's cracking apart after losing her mother—and then something even worse happens that sends her spiraling hard. Meanwhile Kate has built a quiet, beautiful life in the Pacific Northwest with her husband and daughter. She's happy, genuinely happy, for maybe the first time in decades. Then Tully crashes back into her world, and everything Kate has carefully constructed gets tested in ways she never expected.

Hands-On Review
By page fifty I was already annoyed with Tully. She's self-destructive, selfish, and pushes away everyone who tries to help. That's the point, though—Kristin Hannah doesn't let you off easy. You have to sit with your frustration and then, slowly, understand where it comes from. When the backstory about her childhood unfolds in fragments, I found myself putting the book down just to stare at the wall for a minute.
Kate is the heart of this sequel in a way she wasn't as much in the first book. Here she gets to be fully herself—not just Tully's shadow or support system. Watching her navigate motherhood while Tully unravels was the part I stayed up late reading. There's a scene where Kate confronts Tully about her behavior that I reread three times because it felt so real, so earned.
What surprised me was how slowly the middle section moved. Around page 200 to 300 I felt the momentum dip. The plot pushes forward but the emotional intensity backs off, and I found myself picking up my phone more than I should have. I almost put it down. Then chapter thirty-seven hit like a truck and I didn't stop until the last page.
The ending won't be for everyone. Without spoilers, I'll say it feels honest rather than tidy. I closed the cover and sat quietly for maybe ten minutes. That's always my real test—was the ending worth the journey? For Fly Away, yes. It mostly was.
Who Should Buy It?
- Firefly Lane fans who need closure – if you ugly-cried through the first book and still think about Tully and Kate, this is for you
- Readers who enjoy emotional women's fiction – think Jodi Picoult or Emily Henry vibes, but more literary
- Book club groups – there's plenty to discuss about friendship, loyalty, addiction, and forgiveness
- Anyone who likes character-driven stories – the plot is secondary to the emotional arc here
- Skip this if you prefer fast-paced thrillers or want a book you can read at the beach without crying in public
Alternatives Worth Considering
If you want something with similar emotional weight but a different story, try The Women by Kristin Hannah (her more recent bestseller set in the Vietnam era) or Little Fires Everywhere by Celeste Ng for another take on female relationships and secrets in a small town.
For a lighter read after this heavy book, Beach Read by Emily Henry offers emotional depth without the weight—still thoughtful, but with more humor threaded through.
FAQ
Absolutely yes. Fly Away is a direct sequel and references events, relationships, and outcomes from the first book constantly. You'll be lost without it.
Final Verdict
The Fly Away novel isn't trying to outdo its predecessor in dramatic twists—it's trying to go deeper. It asks what happens to friendships when one person keeps failing and the other keeps forgiving. I had my doubts around the halfway mark, but by the end I was genuinely moved. Kristin Hannah knows how to land an emotional punch, and this book delivers it. If you read Firefly Lane and loved it, you'll want this on your shelf.
