To the outside world, Electra D'Aplièse seems to be the woman with everything: as one of the world's top models, she is beautiful, rich and famous.

Yet beneath the veneer, and fuelled by the pressure of the life she leads, Electra's already tenuous control over her state of mind has been rocked by the death of her father, Pa Salt, the elusive billionaire who adopted his six daughters from across the globe. Struggling to cope, she turns to alcohol and drugs to ease the pain, and as those around her fear for her health, Electra receives a letter from a complete stranger who claims to be her grandmother . . .

In 1939, Cecily Huntley-Morgan arrives in Kenya from New York to nurse a broken heart. Staying with her godmother, a member of the infamous Happy Valley set, on the shores of beautiful Lake Naivasha, she meets Bill Forsythe, a notorious bachelor and cattle farmer with close connections to the proud Maasai tribe. When disaster strikes and war is imminent, Cecily decides she has no choice but to accept Bill's proposal. Moving up into the Wanjohi Valley, and with Bill away, Cecily finds herself isolated and alone. Until she discovers a new-born baby abandoned in the woods next to her farmhouse . . .

The Sun Sister is the sixth breathtaking instalment in Lucinda Riley's multi-million selling epic series, The Seven Sisters.
