I was sure I couldn't have been the only one to have developed systems and ideas for running zero-level characters before they started life as full adventurers in 5e D&D, given the importance now placed on thinking about each character's earlier background. This supplement certainly provides some ideas I'd not thought of - as well as some I had! - and a more detailed system to run adventures generally for such "lowly" folk.

As with all such innovative things, it's often difficult to be sure how it will run in game-play, but at the very least, there's plenty here to work with and tweak, if necessary. For those to whom this concept could be of interest, I'd be happy to heartily recommend it.
