A Fist of Permutations in Lightning and Wildflowers, by Alyssa Wong

Now this one, A Fist of Permutations in Lightning and Wildflowers, is pretty good.  A very intense relationship between sisters, sisters with weather working powers, and one of them suicides in pretty spectacular fashion.  The other tries to work through alternate timelines to bring her back.  Pretty darn cool and enjoyable, I would recommend it.  Strong 3 stars.
