Dany Ashton is invited to vacation at her stepfather's house in Zanzibar, but even before her airplane takes off there is a stolen passport, a midnight intruder--and murder. In Zanzibar, the family house is Kivulimi, the mysterious "House of Shade," where Dany and the rest of the guests learn that one of them is a desperate killer. The air of freedom and nonchalance that opened the house party fades into growing terror, as the threat of further violence flowers in the scented air of Zanzibar.
