Some excellent short stories about the immortal cyborgs seeded through time by the time-travelling company as part of an immense scheme to make immense amounts of money in the future when discoveries and antiquities carefully hidden for hundreds or thousands of years and which can now be sold for a mint. Life ain't easy for an immortal cyborg and there are always difficulties and problems to overcome, to say nothing of the machinations of both the Company masters and of certain powerful immortals who think they'd be better off in charge. Baker writes engagingly, it's easy to become addicted.
