What's it about?

Wanda Maximoff, aka the Scarlet Witch, is a mutant with magical, reality-altering powers.  After a traumatic event wherein she kills some of her fellow Avengers, the X-Men decide that she needs to be reined in.  Her brother Pietro, aka Quicksilver (he's a speedster), and her father Magneto (the X-Men's main enemy), want to save her and so spirit her away.  The Avengers and the X-Men go in search of the missing family but before they find anyone the world turns white and changes.  Suddenly, mutants are in charge.  They are running things and aren't victimised.  Magneto is a sort of benevolent leader and homo sapiens (us normal humans) are the oppressed.

Only Wolverine can remember how things used to be, so he sets out to put things right.

The Gods are dead.  Destroyed in the last great battle, Ragnarok, Thor exists in the void.  Called back to a shadowy dreamscape by Donald Blake, his human alter-ago, they consider their role in life, or even ifthey desire a life. To live, to return to earth, proves a sweet temptation for Thor and so he returns.  The other Gods are asleep, trapped in human bodies and Asgard has to be rebuilt.  As Thor travels the earth searching for his lost brethren he discovers the tragedies that have beset mankind in his absence, and comes across a few old enemies.
