Flashback ( PDFDrive )

Thunder clapped and lightning flashed when the light and darkness
collided, hurling both Wylie and Umber backward as the force
exploded.
Sophie tried to cover her head, her vision dimming from a fresh
surge of pain. But she could still see the waves of shadowy light whip
in every direction, spinning into a cyclone and spreading wider and
wider until it burst with a blinding flash that somehow blacked out
the sky.
More crackles and flashes followed. And when the air finally
calmed, all of the force fields were gone.
All of them.
Sandor must’ve realized the same thing, because he raised his
sword and charged.
And when Ruy tried forming a new force field, the energy flickered
and dissipated.
So did Umber’s shadows.
“Well,” Gethen said, frowning as Sandor closed in, “looks like we’ll
have to finish this another time.”
He reached into his cloak, pulling out a cobalt blue crystal and
holding it up to the sky. Ruy and Umber did the same, calling, “See
you soon,” before they stepped into the light.
The last thing Sophie heard was Dex telling her to hold on. Then
someone lifted her off the sand, and her consciousness slipped away.
