One of the things I like about this series is, despite being a collection of three mysteries, the books themselves don't feel like they're rehashing the same plot over again. Acatl grows as a character throughout the series and the challenges he faces, both intellectually and emotionally, reflect that. Ad the mystery elements are also excellently done. De Bodard never resorts to making her detective stupid for the purposes of the investigation and it feels as though Acatl is always one step ahead of the reader. I thoroughly enjoyed this series and will definitely track down Aliette de Bodard's other works.
