Honestly, the series had already halfway lost me by the scene in the middle of book 2 where her reincarnated true wuv - y'know, the one who's life she'd nearly got herself killed saving at the end of book 1 - gets killed off in some random bomb blast, and is hardly mentioned again. Wasn't even particularlly epic or tragic just, whoops, now he's dead. Talk about anti-climatic.

After that, the aliens/Jesus/vampire baby/imaginary boyfriend WTF seemed more like the logical direction for the rest of the books. My only excuse is that at that age I was in the habit of finishing every series I started, no matter how weird it got.
