Quinn Thomas' brother, Parker, has been missing for more than a decade when, as an empath, she's mysteriously drawn to a cache of his letters, hidden away in her parents' attic. His letters speak of her special power and his pride in who she is and what she can do.

It's confirmation that he's never forgotten her. But where is he? And why, given the empathic abilities that used to connect them, has she felt no spark from him after all these years?

Tucked inside one of Parker's letters is a vibrant drawing of the sun. Parker is a skilled artist and the sun is his adopted symbol. Quinn is shocked when the emblem inks itself onto her arm, creating a guide that seems to be trying to tell her where her brother may be.

That's validated when Quinn visits a local tattoo artist who tells her she is a conduit to her brother. The tattoo comes alive when Parker's presence is near, but his appearances are the stuff of mirage and hologram: He's real and not real.

With their mother's cancer diagnosis creating a very real deadline, Quinn is determined to bring her brother home, but the seething sun tattoo and his flickering image seem to warn her that he's in grave danger. Frustrated, Quinn finds help on her quest from Braden, Parker's best friend and lover from high school; Quinn's best friend, Candi, and one of Quinn's rehab clients, Toby. Even with their help, will she find Parker in time to save him?
