Now in one titanic tome: the entire chart-topping run of super-team Joss Whedon and John Cassaday! Winner of multiple prestigious Eisner Awards, Whedon and Cassaday's Astonishing X-Men was a smash hit with critics and fans alike from the very first issue - winning praise from dozens of top media outlets including Entertainment Weekly, Publishers Weekly, TV Guide, and New York Magazine, as well as racking up nearly every major comic-book industry award. Buffy the Vampire Slayer creator Whedon and Cassaday (Captain America, Planetary) assembled a tight cast - Cyclops, the Beast, Wolverine, and Emma Frost, joined by returning fan-favorite Kitty Pryde - and set forth a groundbreaking pace, from the opening pages of a Sentinel attack to the unexpected return of a beloved X-Man. Then, building on early momentum, they ratcheted up the danger and drama with a shocking second year, creating a must-read book that can truly be called "astonishing!"
