They kind of got there HEA. They both had to die first, but still. I wasn't sure what Apollo was planing until he started talking about the river of forgetfulness, which I didn't write down the name of.
I'm glad Artemis changed over the course of this book. I didn't like her at the start of it, but by the end she was a lot better. Her not being a Virgin goddess was kind of odd. I don't know why, since she's not a virgin in the Dark Hunters either, but still.
