Both Uncanny Avengers #1 and Red She-Hulk #58 the first in a line of titles to get the Marvel NOW treatment has now sold out at Diamond and Marvel will be bringing both back with second printing variant covers.
Uncanny Avengers #1 is from writer Rick Remender and artist John Cassaday, in the wake of Avengers Vs. X-Men; Captain America realises that he needs to do more to build a peaceful co-existence between mutants and humans and approaches Alex Summers aka Havok to lead an Avengers team made up of mutants and heroes.

Betty Ross is the Red She-Hulk, the Red Hulk title rebranded with issue #58 under the Marvel NOW banner and with the Red She-Hulk taking over the title from the creative team of Jeff Parker, Carlo Pagulayan & Wellinton Alves. General Fortean returns to build bigger, better super-soldiers and Betty Ross must do everything she can to stop him without destroying everything first.
