Interestingly, at the end of that chapter Thrakhath muses to himself why the humans didn't attack the Emperor's palace... seems like Forstchen was alluding to the future Behemoth/T-bomb strikes, and Thrakhath's obsession with attacking Earth. Of course, this calls into question why the Tarawa didn't sacrifice itself to end the war.
Somebody wrote on Amazon.com that Fleet Action was better than End Run... I can't believe what they were thinking. Maybe it's because Fleet Action has a bigger battle scene. *shrugs*
