Cillian is no stranger to the pull of dark magic as he is the son of both the Dark realm Princess and the Light realm Prince. What doesn't help is that he may have been further infused with dark magic as a child, during an abduction. The only person with insight into that, however, is not talking.

When Cillian finds himself drawn to a human woman in the dream realm, he discovers his dark nature may be worsening her health in the waking realm. Despite trying to reverse this by no longer visiting her, he will find it's harder to give up their visits than he thought.

Annabelle has lived a difficult life and after many years in foster care, she has finally aged out and is trying to make her way and figure out her medical needs at the same time. Her fatigue has worsened since she began traveling but she has found a doctor willing to see her for free. While navigating her life, she finds escape in the form of a mysterious dream man who gives her hope and listens to her worries. When he abruptly announces he will no longer be in her dreams, it's as devastating as losing a real-life friend.

When things worsen in Annabelle's waking life, will Cillian merely observe and allow things to proceed or will he intervene? Will Annabelle understand Cillian's fae world and the magic he has?
