Raveler

Assassin's daughter. Sorcerer's son. Nothing in common but being on the run.
Fang assassins eliminate challenges to the Ari Empire. Amryn has trained in the killing arts since she was old enough to hold a blade, but science is her calling. As an Acolyte of the Unraveling, she would pursue knowledge instead of dispensing death. But her father is the emperor, and her mother is the Fang commander. So much for options.
Hobi struggles to understand the gifts he inherited after his father was murdered. Water and fire answer his command, though he has no idea why. It's hard enough being N'si without also being a freak sorcerer. Then a stolen journal burdens him with a duty he cannot deny. Find a lost homeland before the last of his kind fade away.
Amryn flees an ambush. Hobi eludes the Fang's vengeance. Luck lands them together on his expedition into the Endless Ocean. Their search for a lost city uncovers the unspeakable horrors of an ancient evil.
To free Maurya from its grip, they risk a fate worse than death-losing body and soul to the Elders.
Magic and bioengineering. Sorcery and sunken spaceships. Fantasy with a sci-fi twist.
