Codex Born is a fun fast read, well suited to a flight from Canberra to Perth. It is another desperate adventure for Isaac Vainio and Lena Greenwood as they discover dark, hidden, truths about their world.
As to what those surprises are, well, there’s the [SPOILER DELETED] and also the [SPOILER DELETED].
About the only complaint is the sense of middle book syndrome, and wondering how much of the loose ends were deliberately inserted to support what I presume will be the final volume of the trilogy.
Incidentally that’s not the cover to my version – that has Isaac rather than Lena on the cover, but I think i prefer this one.
Other than that, if you enjoyed Libriomancer, you’ll enjoy Codex Born.
