"There was a new maturity in her dark eyes, a confidence that wavered only briefly. An urge to dismantle it—dismantle her—rose within me. Could she tell?"

Sharing your body with a controlling alien who invades your mind in fervent lucid dreams is no walk in the park.

When Kak first entered my life, I fought tooth and nail to resist his influence. Yet over time we bonded in perfect harmony: two souls in one body, synced and molded to each other's needs and desires.

But our peace is shattered by the return of Kuthil Ash Kharn, the alien who implanted a shard of himself inside me all those years ago... The shard that became Kak. Is it even him? Or has a decade back on his Home world turned him into someone... something... else?

There's a new darkness inside Kuthil Ash Kharn that's impossible to ignore. It both alarms and allures me, beckoning me to the edge of an unknowable abyss. My first instinct is to run the other way and continue my idyllic life with Kak, but I can't. Not yet. Because people are dying, and the aliens seem to be involved. Now I've got one last job to do, and I need Kuthil Ash Kharn's help to do it.

Will Kak and I survive this? Or will Kuthil Ash Kharn's haunting allure fracture what took us a decade to build?
