What's the Name of That Book??? discussion

I've been searching for this book for years. I can't remember exactly when I read this, but it may have been sometime between 2015-2018.

Two girls who are on a winter school break, are driving to the lodge and possibly planning to go hiking/camping. They end up getting snowed in the car. They get out and find a shelter. Two guys show up to the cabin, one is a criminal and the other has a mysterious background. They make the girls take them to the parents' cabin. They get split up and the main character ends up traveling with the mysterious guy. She starts falling in love with him, but thinks he murdered someone because he has a girl's diary in his backpack. It turns out it's his sister's who was either lost or killed by someone. They make it to the cabin and they find out the other girl's brother murdered the guy's sister.

Black Ice by Becca Fitzpatrick?

Kirkus Review:
- "Britt wants to go hiking in the Tetons as she tries to recover from the end of her romance with Calvin Versteeg. She and Calvin’s sister, her best friend, Korbie, set out for the Versteegs’ palatial cabin but break down in the middle of an unexpected blizzard. They trudge through the snow and find a cabin occupied by Mason and Shaun, who reluctantly take them in. Soon, however, the girls learn that the young men are on the run from the police and intend either to kill them or take them hostage. Britt talks them into leaving Korbie behind while she accompanies them as their guide in a hike toward the highway, where Mason and Shaun plan to steal a car and escape. ..."
