Seventh Journey (Electronic book text)

Netex, an advanced research firm with more than one secret agenda, has developed a mind-altering headset technology which now poses a threat to all of humanity. The headset uses a mysterious sound wave called "Auditum" that can control the brain and even hurls users into a different dimension.

Staff scientist Jacob Cross has been deeply involved in developing this new headset and was lead to believe the technology would serve various medical applications. Now terrified that his invention will be used to enslave millions, Jacob sends himself through the dimensional portal. There, Jacob falls in love with the powerful yet ghostly Tamara, who warns him that the fate of both their worlds are now linked by a shared peril. Tamara's world has fallen prey to a monstrous adversary who now threatens to destroy Jacob's world as well.

Jacob awakens, only to find his real life turned upside down as he is caught in a murderous plot created by the CEO of Netex. His loyalties are quickly torn between the two linked dimensions, causing Jacob to question his own sanity and even his ability to know what is real-and what is not.
