the name faolan itself means wolf, fao means both river and wolf while lan means gift so yes in irish this would mean wolf.
anyonewho read the maldach series wuold know what it means
Faolan means "gift from the river".
A wolf from the wolves of the beyond fao means river and wolf lan means gift
There's a bit about the cover on the author's blog. From what she said it sounedd like it's just going to have some foiling added and the shade of color will be slightly different. But still the same picture.
