Age range 14 to 18 

In the second installment of this richly imagined fantasy adventure series, a new threat from within the Library could destroy those who depend upon it the most. 

The Library of the Unwritten in Hell was saved from total devastation, but hundreds of potential books were destroyed. Former librarian Claire and Brevity the muse feel the loss of those stories, and are trying to adjust to their new roles within the Arcane Wing and Library, respectively. But when the remains of those books begin to leak a strange ink, Claire realises that the Library has kept secrets from Hel and from its own librarians. Claire and Brevity are immediately at odds in their approach to the ink, and the potential power that it represents has not gone unnoticed. When a representative from the Muses Corps arrives at the Library to advise Brevity, the angel Rami and the erstwhile Hero hunt for answers in other realms. The true nature of the ink could fundamentally alter the afterlife for good or ill, but it entirely depends on who is left to hold the pen.
