The last book to tie all of the ends or cliffhangers which After all that's happened in the previous books this is the one to finish them all and prove Beitech guilty. It sends us to our last pair of characters and shows the side of the story from the Kerenza point of view while the other events are happening. It's a great story with many surprises and anything that's been left out answered. It's a perfect and satisfactory ending which ends our ride through the Illuminae files.
