First in a terrific new series featuring wealthy paranormal party girls--from the author of the Charmed books. The Caruthers sisters are heiresses with privilege, wealth, beauty, and brains. But these party girls have something extra. As the Guardian Keys, possessors of an ancient family secret, they hold the fate of the world in their hands. Gillian, the eldest, is a sensation in the art world-- this world, that is. In her other world she's the Assassin, a knockout who snuffs out dimension-jumpers who foul up her personal space. She never expected to join forces with one. But when a plague of murderous demons plunges the earth in darkness, she has no choice but to get a little help from a being who knows his stuff.

As Internet-based commerce becomes commonplace, it is important that we examine the systems used for these financial transactions. Underlying each system is a set of assumptions, particularly about trust and risk. To evaluate systems, and thus to determine one’s own risks, requires an understanding of the dimensions of trust: security, privacy, and reliability.

In this book Jean Camp focuses on two major yet frequently overlooked issues in the design of Internet commerce systemsв ”trust and risk. Trust and risk are closely linked. The level of risk can be determined by looking at who trusts whom in Internet commerce transactions. Who will pay, in terms of money and data, if trust is misplaced? When the inevitable early failures occur, who will be at risk? Who is “liable” when there is a trusted third party? Why is it necessary to trust this party? What exactly is this party trusted to do? To answer such questions requires an understanding of security, record-keeping, privacy, and reliability.
