Buying Time – Joe Haldeman

In a not so distant future, “immortals” can buy ten to twelve years of extra life at a time through a medical procedure known as the Stileman Proces. The catch? They must give all their assets to the Stileman Foundation each time, and the minimum cost is one million pounds. Dallas Barr, an immortal, becomes aware of a conspiracy to subvert the Stileman Foundation. But the secrets go deeper than that, and he is soon on the run.

A well-paced and interesting science fiction thriller with an interesting premise. Dallas Barr’s journey to stay ahead of the antagonists takes him to various places on Earth, and the asteroid belt, with some very interesting societal models. As is common with Mr. Haldeman, the story veers in unexpected directions, with this one digging deeply into a global conspiracy theme that is just as topical as when the book was written.
