On earth, a boy is falling to pieces. From the stars, a girl sees and hears but must never touch.

Lilly’s time as a human ended long ago. She’s a go-lite now, reborn into the pristine world of Panacea with a duty to fulfill: She must speak to humans and help them through her dreams. She must lift their spirits and make sure the light inside them keeps burning brightly and she is supposed to be invisible while she does it, hidden by the veil between worlds which has never been breached… or so the Elders had always believed.

When Lilly is dragged through her dreamscape to help a human with fathomless green eyes and a crushed spirit, those ancient beliefs are shattered. Is it fate, magic, or a power much greater that has torn open the veil between worlds and brought them face to face? And why can she feel his heart as though it were a missing piece of her own?

As Lilly battles to maintain right from wrong and her harmonious world begins to change, a mysterious, dusty manuscript appears, calling to share its secrets and she is tested by feelings so powerful that nothing can hold them back – not even time, space or death. Little does she know, that with every choice she and the green-eyed boy make, they are spinning the threads of fate that will alter the course of worlds.

Fans of Laini Taylor, Marie Rutkoski and Leigh Bardugo will fall in love with this new fantasy romance series. The Guardian's Heart will draw you into a visionary world, hidden beyond a million burning stars, and leave you believing that magic really does live within us all.
