"Two estranged half-sisters tasked with guarding their family's library of magical books must work together to unravel a deadly secret at the heart of their collection--a tale of familial loyalty and betrayal, and the pursuit of magic and power"-- For generations the Kalotay family has guarded a collection of ancient and rare books. Books that let a person walk through walls or manipulate the elements-- books of magic that half-sisters Joanna and Esther have been raised to revere and protect. The magic comes with a price: Esther fled to a remote base in Antarctica to escape the fate that killed her own mother, and Joanna's isolated herself in their family home in Vermont, devoting her life to the study of the cherished volumes. When their father dies suddenly while reading a book Joanna has never seen before, the sisters must reunite to preserve their family legacy. They uncover a world of magic far bigger and more dangerous than they ever imagined-- and secrets that span centuries, continents, and even other libraries. -- adapted from jacket Provided by publisher.
