Sliver Of Evil - D J Walker - Bog

In the old stories about shapeshifters, they were always fearsome predators.
Until there was Tek . . . a young deer shapeshifter.
In Sliver of Evil, Sho and his younger brother Tek join the large, powerful Ochwah knat when Tek is fourteen. Tek soon learns he has to cope with perplexing, unwanted shapeshifting.
When a cosseted woman of the knat is humiliated, her vengeance is terrible, and in her panther shape she is nearly invincible. Other secret shapeshifters in the knat will try to stop her killing ways. But how much help can Tek, as a young deer shapeshifter, possibly be?
Sliver of Evil is the first book of the 3-book Tek & Nika Series, about indigenous shapeshifters. Warning - In this series, violence is not pervasive, but when it occurs it is horrific. People are beset by depravity, and not all survive it.
