This is a pretty standard mission bo0k. a good spread of mission types and eras. But the best thing about this book is the layout and graphic design. The Art is top notch, as is usual for this awesome Star Trek RPG (this book as possibily the best of i've seen so far), but each individual mission in the book is layed out and themaned for the era that its set in! The Enterprise era layout is particulry cool. There are lots of maps, both of systems, planets, large and small ground areas and ship areas. Generally a fanstastic addition to the line.
