Endless Blue
The appearance of the warp drive from the long lost spaceship, Fenrir, triggers an epic quest for Captain Mikhail Volkov.  According to the drive's computers, Fenrir had been lost to hypothetical 'nowhere' of subspace, but with the drive's housing covered with coral and sea life, obviously Fenrir has gone somewhere.  Faced with genocide at the hands of the alien Nefrim, humans need a miracle to survive.  On the chance that Fenrir's mysterious location holds such a miracle, Mikhail jumps into the unknown and crashes into the endless blue of the Sargasso Sea.  Every ship that misjumped from any race that discovered travel through subspace has crashed into its waters, creating a graveyard of rusting spaceships.  On the Sargasso's great oceans, humans live alongside aliens.  His ship damaged, his younger foster brother lost, and his sanity rattled, Mikhail discovers a secret that might save the human race if he can repair his ship and return home.

Wolf Who Rules
Tinker and her husband, Windwolf, return in WOLF WHO RULES. The action picks up immediately after the end of TINKER. Windwolf finds himself besieged from all sides.  Viceroy and head of the Wind Clan, he had been able to guarantee the safety of everyone in his realm, but faced with an oni invasion, he has had to call in royal troops and relinquish his monopoly of Pittsburgh, which is stranded on Elfhome. He now struggles to keep the peace between the humans, the newly arrived Stone Clan, the royal forces, a set of oni dragons, the half-oni children who see themselves as human, and the tengu trying to escape their oni enslavement.

Meanwhile, Tinker strives to solve the mystery of a growing discontinuity in Turtle Creek. She's plagued with inexplicable nightmares that may hold the keys to Pittsburgh's future. The only clue from the Queen's oracle to help Tinker is a note with five English words on it: Follow the Yellow Brick Road. Oni, and dragons and tengu – oh my!
