Last Guard
New York Times bestselling author Nalini Singh returns to a world devastated by change in her award-winning Psy-Changeling Trinity series, where two people defined by their aloneness hold the fate of the Psy in their hands...
Termed merciless by some, and a robotic sociopath by others, Payal Rao is the perfect Psy: cardinal telekinetic, CEO of a major conglomerate, beautiful — and emotionless.
For Canto Mercant, family and loyalty are everything. A cardinal telepath deemed “imperfect” by his race due to a spinal injury, Canto cares for the opinions of very few — and ruthlessly protects those he claims as his own. Head of intel for the influential Mercant family, he prefers to remain a shadow in the Net, unknown and unseen. But Canto is also an anchor, part of a secretive designation whose task it is to stabilize the PsyNet. Now that critical psychic network is dying, threatening to collapse and kill the entire Psy race with it.
To save those he loves, Canto needs the help of a woman bound to him by a dark past neither has been able to forget. A woman who is the most powerful anchor of them all: Payal Rao. Neither is ready for the violent inferno about to ignite in the PsyNet... or the passionate madness that threatens to destroy them both.

Nalini Singh
When Nalini Singh writes, the impossible becomes intimate. In her worlds, psychic networks unravel under the pressure of suppressed desire, angels rule cities from the skies, and love—bold, dangerous, transformative—is never just a subplot. A master of genre fusion, Singh doesn’t simply blend paranormal romance with urban fantasy; she reinvents what those genres can do, infusing them with emotional intensity and social complexity that linger long after the final page.
Born in Suva, Fiji, and raised in New Zealand, Singh grew up straddling cultures, languages, and landscapes—an experience that left its mark on her imagination. Before becoming a full-time author, she taught English in Japan, a chapter of her life that gave her a deep appreciation for global storytelling traditions and a sense of discipline that now anchors her prolific writing career. That balance between immersive world-building and narrative control defines much of her work.
