Query: Deus ex machina!

The "forever" series seems to be forever declining with each sequel. The thrilling "Forever War" degenerated into the so-so "Forever Peace" and then now, the horrible "Forever Free." Let us hope to be forever free of this series.The book suffers from weak storytelling and a sense of disappointment when what seems to be the focus of the story - the starship excursion - falls out of the picture.The ending is classic deus-ex-machina. Using it is the kiss of death. Nothing in the plot prepared us for the ridiculous ending.
