The Sato Corporation comes to Elderton. The Sato Corporation built the new Crooked Creek Commons parking garage. They bought Blue Devil Castle for their new corporate retreat. They funded the Waverly Perchance Memorial Garden, a project organized by twelve-year-old Dotty Morgan. Now, Mr. Sato himself takes an interest in Dotty and her dream of owning and operating a legit Supernatural Sleuthing Agency. Mr. Sato's interest comes with cash. If Dotty lets Mr. Sato examine the Japanese sword and cup her dad recently acquired, then Mr. Sato will approve a generous small business grant. All Dotty's dreams will come true. Simple, right? Except a lot of people want to get their hands on the sword and cup, including zombie ninjas, a powerful demon called an oni, human/bird hybrids known as tengu, and her new friend, Sakura, whose life might depend on it. Dotty finds herself in the middle of a war between paranormal factions, but she still has to contend with a jealous girlfriend, bullies, and a nightmare houseguest. Middle school is tough!
