The Palace of the High Ones is threatened by a ruthless human warlord, and Cutter makes the difficult decision for survival’s sake to split the Wolfrider tribe in two. Shards follows the trials of Cutter himself as he realizes he – and the remaining Wolfriders – must confront the tyrant on his own ground.

(The story lines of Hidden Years and Shards weave between the two titles. You can bounce back and forth, but it’s easier to read each in turn. Imagine you are bingeing two related TV series – it will all come together.)
