The princess’s hapless demonic guards soon discover that their captive expects to be treated like, well, a princess. Things go from bad to worse—for her captors—when some of Princess Syalis’s schemes end in her untimely—if temporary—demise and she chooses the Forbidden Grimoire for her bedtime reading…
