The author describes this as basically just notes for an adventure, and this becomes clear as you read. The formatting is odd at times, there are obvious typos... and most significantly, they never clearly explain what the players are doing here, other than randomly exploring the town and mansion. You have to infer the player's goal - searching for the titular "Lost Kenku" - from the rest of the text. Now, to be clear, the setting and NPCs are fun, and you can still run this as a perfectly functional adventure... but extra work is required for the setup, which is pretty embarrassing for an official D&D product. Best to see the purchase of this product as a charity donation with some bonus adventure notes.

Ran this as an outpost in ToA, had a lot of fun riffing off of it, and it made for a very entertaining session between story beats. Did almost kill a lvl 5 PC as they were running away, so be careful with the BBEG. The fight in the study was fun too, added in my own magical items and was entertaining.
