SM Reine

Nina Silverhand has never failed to assassinate anyone before Patrician Lorent. When the client tries to kill her instead -- tying up loose ends -- Nina and Lorent agree to team up against their would-be killer. But first they have to figure out who wants his throne, and Lorent has to hope it's not anyone he likes. Nina doesn't take losing kindly. And she's not one for mercy."The Liar's Throne" is for readers who like cross-dressing bodyguards, Dwarf ruins, and an ancient Elf assassin who will kill anyone who looks at her wrong.
This is a 400-page standalone fantasy novel in the same world as "Atop the Trees, Beneath the Mountains." There's no overlap in characters, geography, or time period, so you can read it on its own.
