The Ascent: A Novel

What would you do if the past showed up on your doorstep?

A woman who grew up in a cult must decide if she can trust the stranger claiming to have answers to the dark mysteries of her childhood in “a standout thriller with something deeper on its mind: how the past doesn’t just haunt you, it reshapes you” (The Seattle Times).

“I tore through this book and was genuinely shocked by its ending!”—Ana Reyes, New York Times bestselling author of The House in the Pines


For decades, the whereabouts of The Fifteen has been an unsolved mystery. All the members of this reclusive commune outside Philadelphia vanished twenty years ago, except for one: a twelve-year-old girl found wandering alone on the side of the road.

In the years since that morning, Lee Burton has tried to put the pain of her past behind her, building a new identity for herself with a doting husband and seven-month-old daughter, Lucy. But motherhood is proving a bigger challenge than she anticipated. She doesn’t want to let Lucy out of her sight even for a moment. She can’t return to work. She’s not sleeping, and she has started spiraling into paranoia.

Then a stranger shows up on her doorstep, offering answers to all of Lee’s questions about her past—if Lee could only trust that this woman is who she says she is. Can Lee keep her safe, stable life? Or will new revelations about “the cult that went missing” shatter everything? In The Ascent, Allison Buccola has crafted a nerve-rattling thriller about motherhood, identity, and the truths we think we know about our families.

I enjoyed Allison Buccola's debut novel Catch Her When She Falls, so I was looking forward to reading The Ascent. The Ascent did not disappoint! It's a page turner, had me staying up until two a.m. Twenty years ago, Lee Burton was in a cult - and one day, everyone disappeared, including her mother and little sister. To this day, she's been haunted. What happened? Are her mom and sister still alive? Now Lee is living in the suburbs, the mother of a little baby, when one day out of the blue a young woman shows up claiming to be her long-lost sister. Lee believes her, and takes her into her home. But is this woman truly her sister? Or does she have more sinister aims? The Ascent is told in dual timelines, and both of them have great mysteries. Best of all, the main character and her cult past, and all the mixed emotions she has about it, all feel very real. She's a very easy character to root for, which is what makes this such a gripping thriller!

This book is amazing. Definitely needs to be a movie. And so well-written. The author has also been gracious enough to talk with book clubs! Highly recommend.

This was one of the hands down best books I've read in a long time. The mystery aspect of the story is utterly compelling on pretty much every level. It's engrossing, with excellent characters, and tons of tension. Highly recommended.
