Return to a dark world of deadly secrets in the final instalment of the Fogg Lake trilogy by New York Times bestselling author Jayne Ann Krentz.

Olivia LeClair, psychic investigator, has survived a lot - from paranormal disturbances to murder attempts. So, when the enigmatic Harlan Rancourt - long believed dead - approaches her with a dangerous request, she's less than impressed. According to Harlan, she's the one person who can help him locate the legendary Vortex lab.

Unfortunately for Olivia, she doesn't have much choice: her psychic investigation firm works for the mysterious Foundation, who are determined she assist Harlan. Harlan - shadowy and distant - isn't easy to trust. But before she can decipher his real motivations, they're both pulled into a dangerous game of cat-and-mouse: sinister forces are also desperate to unlock the secrets of the long-lost lab. Worse still, they too are convinced Olivia is the key. Only her unique psychic talent can defuse the ticking time bomb that is Vortex.

While neither trusts the other, Olivia and Harlan have no alternative but to work together to stay alive - and unlock the Bluestone Project's most dangerous secrets before more innocent people die.
