Poseidon's Wake

The last installment of the Poseidon's Children saga follows the Akinya clan, who are offered a chance to clear their name through a message from far beyond the solar system. The signal is traced to a point seventy light-years from Crucible, the world where Ndege Akinya is confined to her home under permanent house arrest because of her part in a disaster that claimed 417,000 lives.

Ndege wonders whether the transmission could have come from her mother, Chiku, who disappeared on a space mission many years earlier. To investigate, Ndege's daughter Goma, a biologist, signs on to the crew of the Travertine, bound for the Gliese 163 system to find out what sent the message. Her trip carries her into the far reaches of space and also back through centuries of family history, where she hopes to find answers to some of the universe's largest questions.
