I'm left hanging in the breeze!

There is no third book damnit.
I'm never going to know what happened. : (
Did David survive the weird mind splitting thing he did or not?
Does the Calliope make it back in time to warn the American govt?
Do the Spanish get the upper hand in the war against the Americans?
Does the Empress smack them both?
Do David and Lara get together?
Or is he stuck fending off the nutty rich girl and her daddy on his own.
THIS is why I rarely start a series unless I know it's finished.
Argh! sigh
Stupid TBR challenge.
