From the Back Cover
For thousands of years the Grigori have lain hidden, dreaming of the day they will emerge from the darkness. Now that day draws close. Norma, Trixie and Ella continue to fight doggedly to frustrate these plans, but they need help. Percy Shelley must lead Norma to the Portal in NoirVille so she can return to the Real World. Trixie's father must convince her that to destroy the Great Pyramid standing in Terror Incognita she has to be prepared to die. And Vanka Maykov - though not the man she knew and loved - must guide Ella to the secret enclave of the Grigori, where she must face the most chilling of enemies. In this explosive finale to the Demi-Monde series our heroes will come to understand that to resist evil requires courage, resolve... and sacrifice.
