The Curse of the Wendigo by Rick Yancey (The Monstrumologist #2)/ ★★★☆☆
Summary: When young Will Henry and his mentor, the Monstrumologist, are called on to save a man from the Canadian wilderness, they must come to terms that perhaps the man that they pull out isn’t the man who went in- if he is still a man at all.
This was his universe, and no doubt, if every particle of light had been sucked from out atmosphere he could have found his way through the utter blackness left behind.
Lost: Purple Quill
