This is a strong collection of somewhat related diagram sets that produce 3D modular origami cubes, dodecahedrons etc. Good for intermediate to advanced levels, although enough information is provided in the work that ambitious beginners would probably be more than able to make the folds. The pictures of completed works are also quite nice for a slim paperback.
More than most modular origami books, this particular one focuses on a range of possible variations on a particular theme, this results in a more detailed series of related pieces, should the folder desire. However, people who are looking for a wide range of dis-similar pieces may find the book a bit repetitive.
I would suggest this book to those interested in modular origami.
