Wrath of the Wendigo: Book 2 of the Chronicles of Crispin Lipton

Things should be settling into a steady routine, but when Crispin Lipton and his friends return to Bristol Manor after rescuing Rylan, everything is far from normal. The strange death of a human girl and the emergence of the feared wendigo serve as catalysts for a harrowing adventure. As Crispin races against time to save the boy he loves and figure out where he fits into his family, he is also forced to come to terms with his propensity for violence.
