The third (and presumably final) chapter in the Spin saga, by Robert Charles Wilson takes the form of Vortex. A worthy successor to the award-winning Spin, and equally fascinating Axis, Vortex wraps up the story of the Hypotheticals, and Earth’s fate from these seemingly unintelligible beings.
Unfortunately, Vortex doesn’t quite capture the same level of intrigue as the previous novels in the series. Though the ending is far-spanning, and reveals the ultimate answers, fans may not find them particularly rewarding. In fact, much of the back story feels grudgingly provided, as if the author only added it as an afterthought. This is not only unusual for Wilson, but disappointing.
