Kara Thomas meets Twin Peaks in this supernatural thriller about one girl’s hunt for the truth about her mother’s disappearance in Kate Alice Marshall’s most commercial book yet.

Sophia’s first memory is of drowning. She remembers the darkness of the water and the briny taste as it fills her throat. She remembers the cold shock of going under. She remembers her mother pulling her to safety before disappearing forever. But Sophia has never been in the ocean. And her mother died years ago in a hospital. Or so she has been told her whole life.

A series of clues have led Sophia to the island of Bitter Rock, Alaska, where she talked her way into a summer internship at the Landon Avian Research Center, the same center her mother worked at right before she died. There, she meets the disarmingly clever Liam, whose own mother runs the LARC, as well as Abby, who’s following a mystery of her own: a series of unexplained disappearances. People have been vanishing from Bitter Rock for decades, leaving only their ghostly echoes behind. When it looks like their two mysteries might be one and the same, Sophia vows to dig up the truth, no matter how many lies she has to tell along the way. Even if it leads her to a truth she may not want to face.

Our Last Echoes is an eerie collection of found documents and written confessionals, in the style of Rules for Vanishing, with supernatural twists that keep you questioning what is true and what is an illusion. 

Thank you to the publisher and Netgalley for an eARC in exchange for a review. All opinions are my own!


Yes. I enjoyed this. But also yes, some of this went over my head.

This is totally CREEEEEPY. Granted, I’m a wimp when it comes to thriller/horror books, but still. I preferred to read this in the daylight hours and I accept that. The mist and twisted souls wandering around had me second guessing every character in the book (with good reason).

I liked the formatting of this one with flashbacks (and forwards) to “videos” of what was happening at different times on the island. Also, who would even want to stay on this island!?!?

What kind of lost me, was the last quarter or so. I didn’t quite get what all of the echoes were doing, who they were following (and why), and a few other questions. A lot more world-building and deeper explanations would have helped me make sense of everything with Sophia and the echoes.

This is a highly atmospheric read and I think that’s why I thought it was intensely chilling. It kept me flipping pages fast and furious to see who survived and made it out alive. I enjoyed the characters and while I didn’t think the sub-plot of romance was all that necessary, I didn’t mind it. I liked that this group worked together to suss out the entities wreaking havoc on Bitter Rock.

Overall audience notes:

  • Young adult thriller/horror
  • Language: some strong
  • Romance: kisses
  • Violence: murder, attacks by supernatural entities
