Avengers / Invaders #7 (2008)

Book Seven: Should Old Acquaintance Be Forgot
Most of the free Avengers go underground to track the Cosmic Cube that's causing so much damage, and learn who is actually using it, though that knowledge may not be terribly helpful for them. Meanwhile, the rest of the teams work to free the captives, but given the attempted LMD coup, the intentions of some of the team members may be misunderstood.
