Last Chance - T. G. Ayer - Bog

The 3rd instalment in the DarkWorld: SkinWalker series.
With the loss of her sister still weighing down both her conscience and her heart, Kailin Odel must take on the next part of her mission - find her mother and Anjelo and bring them back from Wrythiin.
Kailin uses her mother's portal key and enters the Wraith world intent on saving the ones she loves, but from the moment she arrives her mission is fraught with peril.
Arriving in Wrythiin, Kai steps right into the middle of a Wraith rebellion. And only to find that though Anjelo is safe, her mother is held captive by a subversive faction of Wraiths once led by the Wraithlord that Kai had killed.
From Wraiths to Shapeshifters, rebel causes to fraying family ties, to inexplicable new powers, Kai must fight her darkest demons while entering the blackest pits of Wrythiin to save her mother.
