I got a package from Shay (from Andrea Cremer's Nightshade) today. I haven't started trying to figure it out, but I'll put up the pictures for anyone who wants to give it a shot.
EDIT: I've figured out the messages
The first one says: "The mind of Alistair was entertained by fighting and books at a Conatus institution in Scotland."
And the second one had three:
"The keepers devour the peaceful school"
"14O5 (the "O" could be a zero, I'm not sure) a shrill battle"
"The war is over."
