The Gateway Chronicles 3: The White Thread

For a year, Darcy Pennington has agonized over the fate of her dear friend Yahto Veli who sacrificed himself to set her free at the end of her last year in Alitheia. As her third trip to the magical land approaches, Darcy wonders if the daring rescue she desires to launch will be allowed to go forward. Darcy soon comes to realize, however, that much more is at stake than merely the rescue of her friend. Her return to Alitheia is marked by the mysterious disappearance of Colin Mackaby, and a new message from the Oracle adds to the riddles that the Six must decipher if they are to expell Tselloch from the land. Along the way relationships will be created and destroyed, and for some characters, the deepest scars are those that cannot be seen.
