The Lunatic's Curse

Treachery, greed, wickedness, revenge... lunacy.
The town of Opum Oppidulum is home to the freezing Lake Beluarum and its rumored monster. On an island at the center of the lake is an asylum; no one has ever escaped it. So how will Rex, whose father, Ambrose Grammaticus, has been imprisoned there under false pretenses, prove that Ambrose is not insane? And if Rex can free his father, will his evil stepmother drive them both to madness?
Higgins' fans will devour this deliciously scary tale, a "polyquel" to her previous books, all of which can be read singly or together. But not in the dark...
