This is Carl's Brain
Trio of Sorcery by Mercedes Lackey

I had never read anything by Mercedes Lackey before, so I figured this collection of novellas would be a good place to start instead of jumping into a series.  I was pleasantly surprised by the quality of the writing and how much I enjoyed the stories.  The three stories all featured a female protagonist who is capable of performing magic.  They were all intriguing and well written with different settings both in geography and time.

 

I enjoyed the first story the most where the protagonist was a Harvard college student who was helping the police investigate a missing girl.  What I liked most about it was the collection of characters and how Diana, the story’s protagonist, used these non-magical people to help her in her investigation.  The second story, with a Native American ghost controlling a woman was also neat.   The least of stories was the final one where a Wendigo was taking over a video game and threatening to enter the real world.  In that case, believability was a serious issue and I had a hard time buying into the story, but I still enjoyed reading that one as well.  I give this collection a thumbs up and would definitely read Mercedes Lackey again.
