Poseidon's Wake is the third and (currently) the final volume in Alastair Reynolds's Poseidon's Children series. There's another time skip forward, different members of the Akinya family taking the spotlight. The novel has interesting details and numerous story points to continue from but the plot drags in parts, the ending is unnecessary and forced, and character relations are painful to witness -- the book reminded me a lot of the author's 10 years older novel, Pushing Ice.
