2Long ago, the Great Sundering ripped the universe apart, creating two separate realities. The kuldain realm developed advanced technology, and its inhabitants travel the universe on massive ships to colonize and expand their empire. The aether realm, meanwhile, harnessed the magic of the massively powerful eldrich energy that connects everything within their realm. Now, a tentative peace reigns between the two realms, maintained by a treaty and by the Imperial Investigative Service--a force designed to monitor interactions between the realms and ensure that most kuldain inhabitants don't even know aether space exists. Leilani Falconi, a talented agent of the IIS, polices the galaxy with quick sarcasm and a quicker temper. When a series of suspicious deaths in kuldain space threatens the secrecy and peace, Lei must solve the mystery--fast--before both her realities change forever.
