Amnesia

Deception runs deeper than the canals in Verdholm.
Traveling to the Theln lands will be dangerous and possibly deadly, forcing Sam to ask for help from an unlikely ally. What she learns reveals how she is woefully underprepared for the journey, but she doesn’t dare wait any longer. Her brother’s life might depend upon her ability to reach him.
While Sam prepares, Alec uses the newly discovered secret of the canal eels to try and understand the key to making easar paper. A visit with his father reveals that his deception runs deeper than Alec had ever imagined and that his mother might hold the key to what he’s searching for.
Just as Sam and Alec think they understand what must be done, a shocking revelation proves another deception, one that threatens not only the safety of the city, but of the ruling Anders family. Somehow, they are the only ones able to challenge a foe who has planned an attack for a decade or longer, leaving them to question everything they have learned about themselves.
The penultimate volume in The Book of Maladies.
