Cursed

As an intern librarian at the New York Public Library, Penelope Harp gets to work with the thing she loves most: books.

When she is transferred to the rare manuscripts division, she makes a startling discovery. She comes across an ancient tome, purported to be written in an unknown language, yet Penelope can read it just fine.

Inadvertently opening a portal to Hell, she must act fast to close it before Earth is overrun. But her tome is only one of three, with the other two opening portals of their own on the other side of the world. Penelope must travel to the British Library in London and the National Library of France, in Paris, to complete the ritual before it's too late.
