Thin Air [Rachel Caine]
Saving the earth is officially David and Jo's job. That's a scary thought, but then it always had been, really.
Her memory loss was a little confusing, sense I knew so many things that she didn't remember. I hate books like that, they always seem to make me mad. But it was a plot device, so I'll let it go. Really :)
I'm glad Imara isn't really dead. I'd been wondering how Jo was controlling Earth when she'd never had the ability before. I'd expected her to gain the ability, so that would be one way to do it :)
