Copper beach - Jayne Ann Krentz

Within the pages of very rare books, some centuries old, lie the secrets of the paranormal. Abby Radwell's unusual psychic talent has made her an expert in such volumes - and sometimes has taken her into dangerous territory. After a deadly incident in the private library of an obsessive collector, Abby receives a blackmail threat, and rumours swirl that an old alchemical text known as The Key has reappeared on the black market.

Convinced she needs an investigator who can also play bodyguard, she hires Sam Coppersmith, an expert in paranormal crystals and amber. Passion flares immediately between them, though neither entirely trusts the other. But when it comes to dealing with a killer with paranormal talents - and a blackmailer who will stop at nothing to obtain an ancient alchemical code - no one is safe.
