Avengers the Initiative Vol. 6: Siege

The last volume of the Avengers the Initiative is all about Justice & his team of Avengers taking down Camp H.A.M.M.E.R. while everybody else is at Asgard.  Even though the camp is understaffed it still has enough men to give Justice's team trouble but their real help will come from within the camp Speedball has returned.  This book also sets the stage for Avengers Academy.  If we are looking at Brian Michael Bendis's Avengers run as a whole the halfway point would be at Secret Invasion.  However that isn't a great stopping point if you are looking for a stopping or jumping on point then the Heroic Age right after Siege is for you.
