it's always great to see people getting into pendragon, as it's been my favorite series and really my favorite thing ever for around six years. it's not always easy to find other people interested in the series (since it's relatively old and obscure) so just to point you in the right direction, i'd recommend r/Pendragon or our discord server if you're ever interested in discussing the series!!
also, i recommend reading the other books by the same author, particularly morpheus road :)
