The Search for Terrann Wilkinson — Mori A. Eagleson

After hurting her ankle in a horse-riding accident, Terrann Wilkinson and her twin sister, Roxanne, are invited to join some friends for an early-fall overnight at a campground in Minnesota. The ankle hinders Terri's progress when the group goes on a hike and she finds herself falling farther and farther behind. By deviating from the path, Terri hopes to make it in time to fall last in line without being missed. The problem is, somewhere near the middle of the field, Terri suddenly disappears. When the others discover that she is missing, the search is on. The time is getting late and a dark, cold night is developing as the search continues.
