This is a truly great work containing 50 new creatures, full page portraits, and system-neutral creature statistics and descriptions. The table of contents is great with small, circular tokens of the creatures next to the entry. Since the names of the creatures are as fantastical as their image, this is helpful in finding the beastie later.
Each creature entry is very detailed and well written with game statistics including category, characteristics, protection, attacks, and powers. The descriptions are detailed coming close to a full page in length for most entries. The generic stats are akin to most of the d20 systems with which you're familiar but include the normal human range for easy conversion to any RPG.
There are two pdfs available for download: one on standard letter sized page and another that's smaller in landscape format that will cut the paper required to print in half. The images are draggable into your favorite image manipulation tool so you can make handouts or tokens for a Virtual Table Top like MapTool. The work is 135 pages in length making this a great value for your game table.
