I'd do nothing but reading if I could (ok, maybe eat some great food, buy some fancy shoes between two books...oh, and spend some quality time with the gorgeous guy I married while I am on reading-break anyway...)
I liked this world-building, the differenct fractions and the ancient history of the desolate ship in the sky.
The romance part was ok too, but to be honest the SciFi Alien part was much better.
The Aliens were really foreign, the author did a quite good job in inventing a very different society.
