This book gives a GM everything they need to more effectively integrate traps into games. The 2014 DMG devotes 4 pages to traps; Treacherous Traps blessed me with 40 times as much. It is filled with pre-made traps ready to drop-in (and sorted by CR category, no less!), guidance on how to effectively use traps in gameplay, create your own, and suggestions for what types of traps to use for different types of dungeon spaces.
If you are the sort of person who finds a title like Treacherous Traps intriguing, you will not be disappointed in what it delivers.
