New York Times bestselling author Nalini Singh will sign and discuss Heart of Obsidian. Though she's traveled as far afield as the deserts of China, the Highlands of Scotland and the temples of Japan, it's the journey of the imagination that fascinates her most. Nalini lives and works in New Zealand.

In 2006, Singh introduced the beguiling and sensual Psy/Changeling world in Slave to Sensation, which spawned a series that has had readers and critics cheering. Throughout the 11-book run, there has been one question that has tantalized fans. Now, in the 12th book, Singh finally reveals the answer to the biggest Psy/Changeling mystery — an answer so surprising we wouldn't dare spoil it.
