I've been a Magic player for many years now (since 1994), and I wanted to explore more of the universe by reading up on the graphic novels associated with the storylines of the cards. Around the Mercadian Masques block, WoTC (Wizards of the Coast) started releasing "Fat Packs," which were a box set that included: five booster packs, two premium "foil" cards, a 20-sided life counter die, and the novel for the set. So, Invasion rolled around, and I decided to buy one, mostly to get the book. When I read it, I was extremely disappointed.
The storyline is OK. J. Robert King was probably told how the characters need to interact, and what their ultimate goal is going to be. But his writing style drove me nuts; short, choppy sentences that high-schoolers are taught not to do. (At least I was taught not to do it) The way he illustrates his writing style is frustrating and almost comical, and after getting through the entire book, I winced knowing that I'd have to get Planeshift and Apocalypse to finish what I'd begun. Eagerly, as the sets were released, I crossed my fingers, hoping J. Robert King hadn't written them, but this wasn't the case. Both of these books were written in the same annoying style, and it completely destroyed any sense of entertainment the book had for me.
I don't recommend this book, or any other written by J. Robert King for the Magic series. Pick up Jeff Grubb's "The Brother's War" instead, if you're looking for a good Magic novel. You'll enjoy that one.
