All pre-orders must be paid in advance to be guaranteed. Your invoice must be paid in order to reserve your copies.
Note: When traveling, I will have a limited supply of non-preordered books. Invoices will be sent out prior to the event and books ordered 3 weeks in advance unless stock is already in hand, at which time the PREORDERS will close and you'll have to chance it from one of the extra copies of non preordered books :)
Thank you so much! I cannot wait to open doors for you to fantastic new worlds!
