As the inhabitants of The Great House and nearby Town of Lockport slowly piece their lives back together following the earthquake, tsunami, and 'The Epic Showdown Battle', all hopes lean toward a return to normalcy. But the status quo can never prevail where evil seeds are sown. Though the spirit witch, Liddy McPherson, is finally out of the picture, the consequences of her evil acts throughout the centuries continue to linger in the lives of the Branch family, and those closest to them. The sinister secrets of the past prevent old wounds from healing and present festering issues years after their occurrence.

After Steven turns up missing, Loraine and the inhabitants once again call upon the immortal gods Poseidon and Zeus to help them; it is determined that another portal exists within the East Wing which can be accessed during full moon cycles, they theorize Steven had stumbled onto it and disappeared somewhere in the spectrum of time. Through the joint psychic visions of both the immortal Metis and Suzy McVea, they eventually agreed that Steven was transported to the year 1697. The only hope of bringing him back hinges on sending someone else in to retrieve him. The gods decided to recall the spirit of Charlotte Locke to perform the task

Meanwhile, in the present, Loraine struggles to manage the household and discovers the horrible truth that others had wandered into the same portal over two centuries, and were never seen or heard from again. All this, while Gerard, the gods, and their allies strategize to fight the ever-resurgent Secret Society. Will Steven and Charlotte ever make it back? Will the mounting complications ever be solved within the Great House? All answers can be found within the pages of the magical, mystical world of Branchview.
