One by One by Freida McFadden (Paperback)

Claire and her colleagues set out on a team-building retreat in the mountains, hoping to repair strained relationships after months of tension at work. What should be a simple getaway turns unsettling when their tour guide behaves strangely and leads them deep into the wilderness. The group soon realises the trail isn’t what they were promised.

A storm rolls in, the guide disappears, and the hikers become trapped with no phone signal, limited supplies, and no idea how to get back. Old conflicts flare as fear sets in, and Claire notices that someone seems to be sabotaging their chances of survival. Items go missing, directions are wrong, and accidents keep happening.

As the situation worsens, the group starts to turn on one another. Claire becomes convinced someone is lying about their motives for being on the trip. Every mistake feels planned, and every step forward reveals another threat.

When the bodies start to appear, Claire has no choice but to question everyone around her. The danger is growing, and the killer seems to be moving faster than the group can escape. She needs to uncover the truth quickly, because someone is hunting them one by one.
