Gonna admit, at first I thought this was going to be some weak product designed around the idea that the dragon heist faction quests are boring. I get it that not everyone likes the quests, but they're outlines for the DM to fill out. Instead, here we don't get the author complaining about W:DH's quests, but just supplying a solid array of quests for each faction. Now I've read two quests for each faction, so I can't speak to the entire supplement, but everything in here seems to be well written and is more or less complete.
Note that if you're expecting this supplement to be filled with maps and multi branching quest lines, that's not what it is. This is to supply some short side quests for your heroes and that's it.
