Book 2 of Dungeon Academy. This pushes our heroes a new generation and does a great job of building to the next book. Some puzzles and adventures that are written to be appropriate to any mid grade reader. Fun adventure that is not so heavy on Dungeons & Dragons that one would need to know anything about the game to enjoy the series, but a basic familiarity with D&D monster types would be helpful as the are not a lot of monster descriptions. A fun fast read.
