Boasting some twenty different authors this is a sequel to the first book of lairs. The concept is pretty simple, pick a monster and then write a little about what their lairs are like, what adventurers are expected to find there and how DMs can include them in their adventures.

As is usual in these things the sequel covers generally more obscure monsters as the main guys have been covered in the first volume. Still this allows for more original encounters to happen with creatures like the Shedu or Yuan Ti and there are enough famous monsters here (Mind Flayers, Gnomes, Rust Monsters, Minotaurs or Ninjas) to make this worth the price of admission for even more mainstream adventures.

This is not, however, by any means an essential volume. The details of each lair are pretty schematic and short and the DM still has to fill a lot in. Eventually D&D would adopt a different approach dedicating books to particular monster families (such as Giants or Dragons) and their lairs rather than writing books about lairs with a smorgasbord of monsters in them.
