This adventure is great!
A Falling Tower appears and the heroes are recruited to stop it's descent before it crashes into the city!
The players will have a blast as they rush up the tower encountering the remaining residents of a Magic Tower.
If you are using Elementals in your campaign this adventure would be perfect.
There is a great mix of exploration, puzzle solving, and combat with the author sometimes mixing puzzle solving in the midst of a combat encounter which is always great.
The Boss at the end is worth the price of admission. It's a really cool concept with some really cool mechanics that make it challenging but not overwhelming for the party.
This is another must buy adventure especially at the price.
