The books are fun, if not /strictly/ realistic... and I'm saving up
_Invincible_ as the next book to read, where, come to think,
the Alliance ships /have/ already found more interesting things
to look at and /not/ break, including an O'Neill habitat(?)
(It got broke, but not by them.) And more.
Only... not to spoil _Rendezvous with Rama_, but /that/ is about
a rotating-for-gravity cyl inder habitat (an alien one) drifting through
the Solar System, coated with aeons of sense of wonder. Whereas the
Formerly Lost Fleet deals with their encounter object like one more
thing we've all seen many times before. Well, of course, we /have/
(Galactic Whirlpool, Confinement Asteroid, Babylon 5), and also, as
usual, they're in a hurry, but, y'know, play along??? :-)
