I'm a big fan of the monster island setting and was so pleased when I heard about this scenario. A bird in the hand really lived up to my expectations! It manages to include enough detail for you to bring the NPCs and events of Port Grimsand to life whilst not being overly bloated or wordy.
I don't want to give too much away, but the book is almost two adventures in one - your lucky players will get to experience the hustle and bustle of Port Grimsand and it's colourful characters in the first half, before heading into the jungle for an expedition they will never forget.
Additionally the hex crawl rules make travel itself and eventful (and potentially hazardous!) undertaking, especially for the unprepared.
It also helps that the book is layed out in a really intuitive way with everything easily accessible whilst you're running, so you don't have to worry about memorising everything.
Would totally recommend!
