long shot here, but which books will you say are a MUST READ for the new Waterdeep: Dragon Heist (and Undermountain) adventures? You can run them just fine all by their awesome selves!
If you want to add fiction, Elfshadow and its sequels by @e_cunningham, City of Splendors by Elaine and me, and my novel Death Masks.
For more game stuff: Volo's Guide To Waterdeep, then City of Splendors 3e hc and 2e box.
