When you read this, you will likely be as confused about what is going as the characters themselves eventually realize they are. The Team (Both Captain Americas, Iron Man, Thor, Captain Marvel, Black Panther, Blade, Spider Woman and Spider-Man) "wake up" in the middle of an adventure participating in the adventure but not remembering ever starting it. Each issue has a different problem (Captain Marvel being infected by the Dark Tide; Dark Doom invading and Dr Doom joining the Avengers to fight against him; Lots and lots of Red Skulls trying to take over the world; Fighting New Aliens on a New Planet; and playing the game which person on the team is actually brainwashed) but ends with Steve figuring out that the Beyonder must be behind the whole thing.
Overall, each issue is action packed and good, but when read together as a complete story, it takes too long to figure out something is wrong and comes off like you have missed reading issues in a crossover.
Recommend, but with a bit of hesitancy. Hope the sequel "Avengers Beyond" helps fix it.
