This is a very engaging written account of the search to identify the purpose of the Antikythera artifact. Marchant blends together an interest in how driven so many of the protagonists are with an interest in ancient astronomy. This works very well for a reasonably casual-level read, which still respects the subject matter. That Wright clearly chose to collaborate with Marchant does show in the account, but she is scrupulous in trying to show all points of view as modern imaging narrows in the reveal of what the artefact does.
Any GLAM sector employee will likely wince at the absence of airconditioning in a few scenes. And the looting bit. And the dying divers bit - actually, that one goes for everyone. But Marchant manages to make this feel heroic all the same.
