the Silver Branch, by Rosemary Sutcliff

 ...the night itself was very still, behind the sounds the camp. A wonderful night, up here above the mist; the bracken of the hillside frozen into silver stillness below the dark fleece of thorn-scrub that covered the higher slopes on either side, the moon still low in a glimmering sky that seemed brushed over with a kind of moth-wing dust of gold. Somewhere far down the widening valley a vixen called to her mate, and somehow the sound left the silence empty.

—Silver Branch, pg 148

I love Sutcliff's scenery descriptions so so much oh my goodness!
