Wolverine & the X-Men: Alpha & Omega

In 2012, Marvel released this single-issue story bridging the gap between the end of Schism and the launch of the Wolverine & the X-Men ongoing series. Written by Brian Wood with art by Mark Brooks and Roland Boschi, Alpha & Omega pits Wolverine against the vengeful, newly empowered Omega Sentinel, who holds the Jean Grey School hostage. It matters as a tense, standalone chapter that defines the new status quo for Logan's school and his strained relationship with the X-Men's past.
