Trouble is, the poem doesn't work, which makes Fred even fussier—especially when speaking to his friends Luisa and Drake. But while on a quest to find Luisa and apologize, books fly off the library shelves, students nod off at their desk, Drake grows head-snakes, and once again, Fred becomes Frankinschool. But this time, they have no idea how or why. In Book Three of the mysteries, readers set off on an adventure with Frankinschool through secret passageways and grand rooms of a mansion-turned-library. Along the way, they run into old ghost-friends and a few new ones; they learn about managing expectations, anger, and friendships, and discover that sometimes going-to-the-dogs is a very good thing.
