 After book 3's ending, I was desperate to get my hands on book 4 and even when I did - I caved and bought it of Apple's bookstore - it took me a few months to get around to reading it. When I finally did, I was instantly depressed. Kat was indeed captured by Daedalus, and they try to explain that what they're doing isn't as bad as the Luxen have made it out to be. And the killer thing was that Blake - yes, the same Blake who betrayed them - was actually working for Daedalus the whole time Kat and the others were planning their break in to the compound.
