On the surface, Lark Conners appears to be your average college freshman. She likes hanging out with her friends, going to clubs, working out, and exploring her new life on her own. Her two best friends, Trent and Arryn, are textbook examples of intelligent, handsome, and popular college boys. Life for Lark was just what you'd expect but it turned out to be nothing she could have ever imagined.

When an unexpected event turns her life upside down, nothing even her vivid imagination could have devised happens. Her old life is whisked away, and her new life as Sanity Shadowhouse begins. Now, she is the master of a group of preternatural beings, consisting of vampires, lycans, pixies, and other creatures of immense power.

She soon discovers that not only was her picture-perfect life too good to be true, it was also actually a complicated ruse, carefully constructed to keep her hidden from her family's ancient enemies. Once Sanity is introduced to a world of magick and unusual creatures she once dreamed about, she learns that she has abilities people would die or kill for.
