So you guys know the Unlocked cover, right?
Here it is:

Yeah.
So here's a tally of which characters are on how many covers:
Sophie - 9
Dex - 1
Keefe - 4
Fitz - 3
Biana - 1
Linh - 1
Wylie - 1
Tam - 2
Silveny - 2
Linh, Dex, Biana, and my poor boy Wylie, have all been one 1 cover so far.
Silveny's been on 2.
THIS IS A VERY BIG PROBLEM AAAAAAAAAAAAAAAAA
I'm mad.
VERY mad.
Sigh.
Oh, Shannon, author of Keeper of the Lost Cities,
I'm so angry at you right now

EDIT:

Also, SILVENY HAS ABS WHAT THE---

I'll stop now
