This book comes with a Signed bookplate 

Dearest Reader,

I am pleased to inform you that you have made it through the Familiar trials.

Congratulations.

But before we celebrate and make all of your deepest, darkest desires come true, I must remind you of the magically-binding contract you signed when you reached our great city.

Please willingly deposit your blood into the correct blood bank before enjoying the festivities planned.

The trials are over. Now it’s time for the binding to begin.

Welcome to the City of Nightmares.

Fresh out of the Familiar trials, Danni finds herself deep underground in a city full of vampires. Her pursuit for her mother’s killer is etched into her brain, but more than one path threatens to take her off course. One appears in the shape of the city’s vampire prince, Knox. Another will lead her down a dangerous, destructive path of untold power.

Will she stay true to her destiny, or will it be rewritten for her?

Get ready for the highly-anticipated sequel to Circus of Dreams, where every desire has a cost and secrets threaten to destroy it all.
