This module has excellent plug-and-play potential. It does come at the cost of an extremely barebones story, but for me that was no problem. The encounter design is also perfect for showing newcomers to Lancer how to make challenging + interesting enemy compositions, and how to set up battlemaps (something that No Room for a Wallflower notably did not do...at all). The GMing advice for running each combat encounter is extensive and also incredibly helpful for newbies.
My biggest criticism would be that I think the encounters are tuned to be *too* difficult, considering the fact that a moderately balanced encounter in Lancer is more like a hard encounter for newbies. Since this module is clearly marketed toward newbies, I think that's an issue. But at the very least, I suppose one can learn by being thrust into the fire!
If you want to GM Lancer but you're not sure exactly how to start, this book is a must-buy.
