Thank you to NetGalley and St. Martin's Press for an advanced reader's copy in exchange for an honest review!

I'm not normally a mystery/thriller person, and I've never been a huge fan of true crime, so I wasn't sure how I'd feel about this. But the synopsis really pulled me in, and I'm so glad I tried this one - I truly couldn't put it down. Forty years ago, a woman and her infant are found frozen in the Iceland tundra, the woman's throat slit and the baby apparently drowned. The small town of Bifrost immediately assumes the woman's husband did it, although he is never charged, and he flees to America with his son. In present day, the man's granddaughter, Agnes, travels to Bifrost after his death to prove his innocence with the help of a true crime podcaster. Of course, the weekend she arrives, a woman who looks exactly like the women killed decades ago goes missing.

This was a page-turner for sure - I finished it in one day despite the fact that it was Thanksgiving lol, oops - but more than that, Agnes' character growth and her connections with the others involved were really moving and interesting. The twists felt unpredictable, and the stakes felt high both because of the missing woman but also because of Agnes' relationship with her grandfather and desire to understand what really happened. The setting was incredibly atmospheric and spooky, and the writing was gorgeous. The last quarter of the book was amazing and moved so fast, and I was so satisfied at the end. Highly recommend this one.
