From Blood and Ash by Jennifer L. Armentrout

Dozens of fieryy arrows shot into the air, arcing high above the Rise
and then racing downward, slamming into the tinder-filled trenches. A
wall of fire erupted, running the entire length of the Rise. The flames were
no defense against the mist or what came with it.
The fire made what was in the fog visible.
Returning to the window, I threw the latch and flung it open. Cold air
and a kind of unearthlyy silence poured into the chamber as I gripped the

and rooting around until I found the bow. Rising, I tossed it onto the bed.
“You cannot be planning to go out there,” she exclaimed.
“I am.”
“Poppyy!”
“I will be fine.” I situated the quiver along myy spine.
“Fine?” She gaped at me as I turned to her. “I can’t believe I have to
