A fractured past.

A realm of lost souls.

A destiny neither could foresee.

Einar has inherited a legacy steeped in shadows.

Now he must navigate the treacherous expanse of the Halls of Lost Souls and confront the heart-wrenching truth about Agnes, the love he hoped to save.

But the weight of his new role is overwhelming, and the only guide he has is Clara—a fiery and determined woman with secrets of her own.

Clara, the forbidden daughter of the former Arcanist, has spent her life yearning to free the lost souls her father neglected. Now, with access to the halls once barred to her, she seizes the chance to uncover the mysteries of her past.

What she discovers may cost her everything.

Her journey reveals devastating truths about her family, her purpose, and the danger of meddling with forces beyond her control.

As Einar and Clara form an unlikely partnership, their shared pain and determination forge a bond neither expected. Together, they delve into forbidden halls, search for Agnes’s soul, and face the harrowing truths buried in the labyrinth of the dead.

But Clara’s choices unleash a chain of events that threatens to unravel the very fabric of life in Elestra.

Haunted by betrayal and bound by a shared destiny, Einar and Clara must confront their greatest fears—and embrace an unexpected future that could reshape their world forever.

The Arcanist of Souls is the fifth and final novel in The Isles Series by K. Cross, a clean romantasy world filled with butterfly-sized dragons, high seas adventure, forbidden magic, emotional romance, dangerous secrets, and love stories that will take your breath away.
