It’s Aine Balfuinn’s first year attending Penumbra Academy of Witchkind, along with her two sisters Olivia and Beatrix, where they’re taught to hone and strengthen their unique magic referred to as a tether.

But Penumbra is more than an Academy where Witchkind learns to amplify their magic. It’s also the king’s largest recruitment institution for his military. When King Magnus finds a witch with powerful magic, they’re conscripted to fight in his budding war with the Fae. And the King of Witchkind doesn’t take no for an answer.

Aine’s astral projection tether is highly desired magic that the king would stop at nothing to get his hands on. Aine wants nothing more than to hide her unwieldy magic and remain invisible.

But her hold on her magic begins to slip, and Aine has no choice but to make a deal with the audacious and infuriatingly handsome Osric Kilbrock. By choosing to trust Osric, she risks exposing everything she’s tried so hard to keep secret. Because not only is Osric Commander of the Royal Guard, he’s also the Prince of Witchkind. And if he’s going to help Aine avoid the clutches of his father, he wants something in return. The jaws of the King are closing in. And Aine has to make a choice to trust Osric with not only her secrets, but also her heart.
