SPOILER ALERT!
Coffee with Thunderbolts

They come across a Mayan spell which would heal them and take away their regrets, if before New Year's Eve, they can decode the glyphs. The story is about how a Elena used to thinking like a scientist does, starts to believe a spell could cure her. And about how they both realize that healing comes from within and doesn't require spells.
I can see that some people would be put off because the conversations between the character are too formal to sound like real conversations. However, given that the two females aren't like the average person who can function in the society, I think they actually would sound this way.
I liked the humor threaded through the story, it made the book lighter than it would have been without it.
My favorite character was Bit of Nothing.
A good book, not too long and doesn't come off as being preachy.
