This was a fun read. I loved the protagonist's Irish wolfhound, Oberon, and generally enjoyed the book. I wouldn't say it's accomplished—this is a first book, and the sequels could be more polished. What struck me the most was the dialogue. Every character sounds the same, and a very high proportion of the conversations involved bargaining.

The character of "The Widow" made no sense. Fine, he's a nice guy who stops to chat with an elderly woman who sits out on her front porch, and he does yard work for her. But why is he stopping to do yard work when a god is out to kill him, and he really should be spending time at his magically well-protected house or office? And with all the action that takes place at her house, why does she stay such a caricature and is hardly ever referred to by her actual name, but instead always "the widow"?

In an environment where daytime temperatures are often 100, does it really make sense that she sits outside, or that he rides a bike every place?
