a request (not mine) for help

An anonymous commenter has asked if I know of any online plot synopses of the first three books of the Doctrine of Labyrinths. I don't--and before anyone suggests it, I am not, repeat NOT, going to write one myself--but if you do, or have any other helpful suggestions for a reader wanting to get back up to speed before reading Corambis, please reply to their comment. Thank you all.
