Sasha receives an envelope from the king and queen but can't figure out how to open it. When she realizes how it must be opened, she and Wyatt embark on a quest to find all the pieces needed for unlocking the envelope with the special message.
(I'm not sure if there was a miscommunication with the illustrator or maybe it was intentional, but there is clearly an object in one of the drawings early in the book that Sasha says she did not see. However, it is very apparent in the picture...not sure what to think.)
