L. Konisburg, this middle-grade mystery adventure is inspired by the real life of Viviani Joffre Fedeler, born and raised in the New York Public Library.Eleven-year-old Viviani Fedeler has spent her whole life in the New York Public Library. She knows every room by heart, except the ones her father keeps locked. When Viviani becomes convinced that the library is haunted, new girl Merit Mubarak makes fun of her. So Viviani decides to play a harmless little prank, roping her older brothers and best friend Eva to help out.But what begins as a joke quickly gets out of hand, and soon Viviani and her friends have to solve two big mysteries: Is the Library truly haunted? And what happened to the expensive new stamp collection? It's up to Viviani, Eva, and Merit (reluctantly) to findout.

    If she doesn't, she'll lose her magic forever. For most young witches and wizards, it's a simple enough test:ONE: Help your town, do good all around.TWO: Live there for one moon, don't leave too soon.THREE: Fly home by broomstick, the easiest of tricks.The only problem? Eva only has a pinch of magic. She summons heads of cabbage instead of flowers and gets a sunburn instead of calling down rain. And to add insult to injury, whenever she overuses her magic, she falls asleep.When she lands on the tranquil coastal town of Auteri, the residents expect a powerful witch, not a semi-magical girl. So Eva comes up with a plan: set up a magical repair shop to aid Auteri and prove she's worthy. She may have more blood than magic, but her "semi-magical fixes" repair the lives of the townspeople in ways they never could have imagined. Only, Eva's bit of magic may not be enough when the biggest magical storm in history threatens the town she's grown to love. Eva must conjure up all of the magic, bravery, and cleverness she can muster or Auteri and her dreams of becoming a witch will wash away with the storm.
