I feel a little guilty about docking a star from this book just because it wasn't quite what I expected, but I've still gotta go with my gut feeling.
The title suggested similar content to Tomoko Fuse's excellent previous book, "Kusudama Origami"; in that case, there were a few traditional kusudama made by sewing together the points of conical modules to form a globe, but most of the models began with variously decorated square faces which could be attached together (some with glue, some without) to form hollow cubelike polyhedra. Most of those polyhedra required only six face units plus six quarter-square decorations and some simple edge or corner hinges to hold them together, so maybe 8-11 squares of paper altogether.
Instead, this book is closer in spirit to Fuse's "Unit Origami: Multidimensional Transformations". All of the models are based on the same concept, where a fairly large number of rhomboid units (each one actually made of two half-squares) are joined together to form the final shape-- the stellated dodecahedra in most of the illustrations require 30 units each; the slightly simpler stellated octahedra require 12 units each. (There are also instructions to assemble six units into simple cubes, but imho they don't look interesting enough to be worth the effort.)
Once the basic module assembly is established, the rest of the book lays out different cosmetic variations of the same sort of rhomboid units. Some of the units' decorations are made from silver rectangles instead of half-squares. That's all.
It's a beautiful book with even higher production values than "Kusudama Origami", where there were a few full-color photographs in the front but the later diagrams and photos were chromatically squashed down into black/white/red-- "Floral Origami Globes" has full-color photos throughout the entire book, accompanying the clearly drawn diagrams of every module variation.
If you have no objection to the idea of using 30 squares of paper to make 30 identical units for each model as shown in the photographs, then this should be a perfect five-star title for you. Sadly, the prospect already has me dreading deep tedium and the need for lots and lots of paper.
