Most (not all) of the special creatures of Evernight are contained in this pack, as well as 15 or so hero-type characters.
There's one page of directions, and 12 pages of minis.
The minis are slightly smaller than typical "heroic scale" 28mm, so they'll look a little small on most tables when mixed in. They're designed to be used tri-fold, but could just as easily be used as a 2-sided figure in a stand.
The ability to drop down dozens of minis for very low cost is worth it, especially when your players say "what do we see", and you can point them at the artwork from the game as a mini.
Summary: cheap! easy to use! Worth my $8.
