Avengers the Initiative Vol.3: Secret Invasion

Avengers the Initiative kicks it into high gear with a Secret Invasion.  The story is told through two different perspectives, Crusader who is a cadet at the Camp Hammond & a Skrull who has turned his back on the Empire.  The second main character is 3-D Man who is currently part of the Hawaiian team of heroes.  The story goes back & forth between the two characters as they react to learning about the Skrulls & fighting from two different sides back to Camp Hammond.   I really liked the characterization of both Crusader & 3-D Man & I really liked this book up until the last page.  Part of me wishes it it could have ended differently but I don't know how that could have been accomplished.
