There may be an infinite number of Earths out there, separated from each other by a thin wall of probability, each representing a path not taken in another universe.  In between, and separate from them all, lies the sidereal construct of Starhaven, home to the interworld agencies.

Now there are some that say the agencies are just another symptom of the immortals' seemingly innate need to meddle in things that are none of their business.

It's hard to argue that the agencies don't do good work and their activities don't serve some higher purpose.  But conflicts often arise from the various agencies' goals not corresponding well with one another.  Some of the agencies have mutual assistance agreements, but, more often than not, their missions don't travel along parallel paths for very long.

Sword and Shadow

First in the Infinity Prime series, this novel is about the vampire Raven, who has spent the last several years incognito on a backwater version of Earth that bears little geo-political resemblance to the Earth we know.  When he stumbles upon a cache of advanced weaponry, he knows instantly that something important is in the air and he contacts the Crimson Sash headquarters to pass along the information.

In response, Sash gives the data to its sister agency, TAU, the Technological Activities Unit, which then sends their young agent, Valerie Winn, to assist Raven.  The vampire hero is hardly thrilled by this development.  He doesn't consider TAU's mandate to be worth much.  He has entirely too much sympathy for the people who are gathering their forces to rise up against the powers that rule this world.

Val finds Raven's disdain for her agency's rules aggravating, but can't help be fascinated by the way this young-looking immortal being seemed to look right through her.

They must put aside not only their differences, but their growing attraction.  An uphill climb all the way.

Death of Heroes

This first sequel involves a black ops mission organized by the enigmatic ArchAngel into the past of an alternate Earth where the normal humans declared war on their superhuman neighbors.  The resulting war left their world an apocalyptic nightmare.  Recruiting the immortal Morrigan and her compatriot, the vampire Bryon, ArchAngel sends them back into the past to prevent this from occurring.

Morrigan might have spent several thousand years as a killer, but this is hardly training for this sort of venture.  The Knights of Anarchy, Morrigan's new agency, is dedicated to the overthrow of corrupt and tyrannical rulers, but Bryon is more the expert, after his successful mission back to his homeworld after the events in Sword and Shadow.

But ArchAngel is no fool.  He recruits two of Starhaven's most dangerous denizens as backup, unbeknownst to Morrigan.

As things heat up, Morrigan becomes more determined to prevent the war that's coming.  And she's willing to do almost anything to accomplish that task.  If only Bryon doesn't get in the way.
