Maddy is a strong female heroine. She must take control of situations that she is thrown into, seemingly at random at times. Her character is strong, but hasn't changed too much from the last novel in Black Wings series. Satan may be one of the strongest supporting characters. He manages to manipulate the characters without their knowledge; readers know what is going on, but the characters are oblivious.

There are unscheduled deaths occurring in the city of Chicago and it is up to Maddy to discover who could be breaking Satan's rules and eluding his inner circle. Although Maddy tries to keep her cool, she is as mulish as ever, prompting readers to want to hit her over the head and force her to concentrate. There are so many supporting characters in BLACK HOWL that they are hard to keep straight. Readers will get to know most of them quite well and may come to love some while having a different take on others. It is interesting to read about the group dynamic Maddy's "team" has in BLACK HOWL, relationships are changing.

The ending of BLACK HOWL will probably leave you shocked...and dying for the next.
