Within the pages of very rare, centuries-old books lie the secrets of the paranormal. Abby Radwell's unusual psychic talent has made her an expert in such volumes--and sometimes taken her into dangerous territory. After a deadly incident in the private library of an obsessive collector, Abby receives a blackmail threat, and rumors swirl that an old alchemical text known as "The Key" has reappeared on the black market. Convinced that she needs an investigator who can also play bodyguard, she hires Sam Coppersmith, a specialist in paranormal crystals and amber.
