Out of the Depths

While Hannah Prentiss's cousin, Ryder, is exploring the local underground caves not far from Blackberry Valley, he stumbles on a cold case. Inside a remote cave, Ryder finds a backpack filled with personal items that once belonged to their great-uncle. Uncle Chuck was last seen entering the dangerous cave, with its many narrow passages and sharp drops, and there has been no trace of him since.

Howeve...
