This book's author has a very good style of writing battles, but i found the other sections boring and rushed. It's worth reading this book for the epic clashes between dominarians and phyrexians alone, with great war machines killing thousands in one swipe and deadly beetles devouring elves. A word of warning though, Not for the squeamish
The Phyrexian Invasion is the climax of the whole Weatherlight Saga in Magic, so King had an unenviable job to do putting it into novel form. If you haven't read some of the other books in the Saga, especially the Artifacts Cycle and King's own "The Thran" you might be lost in some places, as he refers a lot to those previous books. The Invasion begins right at the beginning, and straight away the book takes you from one battle to the next. They're described in detail as the Weatherlight zips around the masses of Phyrexian ships and the various ground armies tackle the invading drones. However, for creatures that have been genetically engineered to hunt down and kill planeswalkers, Phyrexian intelligence seems to decrease as their numbers increase. Most of the time they just stand (or float in the case of ships) there and get steamrollered by the hundreds. I would have given this book the extra star if it wasn't just one battle after another. The plot does keep developing and it keeps things interesting, but unlike the previous cycles this is just the first part of a single large story, and there's very little difference between this book and it's sequels, Planeshift and Apocalypse.
