Nevada Baylor runs a modest detective agency in Houston, Texas, using her secret magical ability to detect lies to solve cases quietly and keep her family's business afloat. When a powerful firm forces her to track down a fugitive pyrokinetic Prime, Nevada is thrown into the dangerous world of magic's elite — the Houses — and into an uneasy alliance with Connor 'Mad' Rogan, a telekinetic Prime of almost incomprehensible power who answers to no law but his own.

Nevada Baylor is practical, loyal to a fault, and quietly extraordinary — someone who uses intelligence and integrity rather than raw power to navigate a world stacked against her. Catalina Baylor, the second trilogy's heroine, shares her sister's compassion but must overcome a deeper fear of her own terrifying ability before she can fully claim her power and her future.

Across six books split into two trilogies, the Hidden Legacy world is explored first through Nevada and Rogan's combustible partnership and eventual relationship, then through Nevada's younger sister Catalina — a siren Prime whose own story of hidden power, political danger, and romance with the unpredictable Italian Prime Alessandro Sagredo carries the second arc. Both trilogies are complete, each building to a fully satisfying conclusion within the larger world.
