Shadows on the Hill — Jackie Cassada

They were changelings, faerie spirits trapped in mortal flesh.

They were six oathmates, sworn to each other and to the completion of a quest. Together they would search for four powerful faerie treasures that would open a lost gate-way back to their timeless home, the land of the Dreaming--the land of Arcadia.

Their travels take them from San Francisco to the islands of Hawaii, where the mysterious menehune--the faerie spirits of the Pacific isles--hold secrets long forgotten by their western cousins.

Yet even as they pursue their goal, others are sworn to stop them. Backer by the forces of the Unseelie Shadow Court, the Forsworn Prince also seeks the way back to Arcadia, for his own dark purposes....

Continuing the saga begun in The Toybox, Shadows on the Hilt is the second volume in the Immortal Eyes Trilogy.
