This is a wonderful collection of encounters. They lend themselves to easily fit in with pre-existing campaigns or can be played on their own. The short low level encounters are great if you have new players who want to test the waters (pun totally intended) and try some D&D.
For new DMs or anyone wanting to try DMing the layout and story structure for each is very easy to follow.
The encounters have lots of great RP opportunities as well as exploration and combat. Great collection to have on hand for spur of the moment games, or as additions to ongoing campaigns.
