​Alpha and Omega is the beginning of the Alpha and Omega series, a spin off of the Mercy Thompson series. This is a novella that was originally published in a collection, and then published individually. Technically, the happenings of this book happen around the end of the first Mercy Thompson book. However, it was published after the second book.

The story is not very long, there is no world building in the story. If you have not read the other series then you may be a bit lost as to what is going on. However, the characters are extremely well developed. There are several new characters in this story. There are also characters that are only briefly mentioned in the Mercy Thompson series that are better represented here.

I do not usually enjoy novellas. However, I enjoy this one everytime I read it. I think it helps to know that it is just an introduction to a world, and that there is much more left to read.
