By chance, eleven-year-old twins Nate and Herman Howe meet Mrs. Weatherby, a retired member of the Los Angeles branch of Witches Bureau of Investigation. The boys ask her to help find their mother, who has been missing for six months. Reluctantly, Mrs. Weatherby agrees, though all of her licenses to work magic have expired. She reaches out to her old colleagues, for information and assistance, but they soon uncover a dangerous plot that threatens the safety of the entire world. The Bureau may be compromised, so it's up to Mrs. Weatherby's band of old agents to follow the clues and keep the horrors of history from resurfacing.

Twins Nate and Herman Howe are back in this follow-up to WBI: Witches Bureau of Investigation. An ancient demon is running amok in Los Angeles trying to perform a complicated ritual that will give him solid form. He disables the Bureau but fails to account for Mrs. Weatherby and her network of retired witches, who are determined to stop him.

From: Brigitte Constance Larue To: Zofia Goldwater Anderson Larue Dear Mother, A thousand apologies for neglecting to call you on your birthday. I know it's impossible to forget, being on Halloween, but I have a good reason. No, I was not shopping, I was busy saving the world with Mrs. Weatherby. Yes, you read that correctly, my idol, the witch I aspire to be, Agnes Weatherby, former director of the Bureau, who can still work the mojo. I have attached a PDF file (call me if you can't download it or read it) of my official report. I won't say much here or risk spoiling all the surprises we encountered. I will tell you that your former bridge partner and extraordinary orangutan Clementine was along for the ride. Also joining us was WBI's newest recruit, Kitty Howe, and her twin boys, Herman and Nate. I do believe that trouble follows those boys like paparazzi. Herman broke an hourglass that belonged to Death and managed to find himself—oops! No spoilers. Read my report and call me. Kisses, your youngest daughter, Brigitte.
