Fathomless (Redemption's Heir #2)

Sean Wyndham has tried to stay away from the lure of magic—the last time he tried to dabble in the dark studies, he inadvertently summoned a blood familiar, wreaking havoc on his town and calling the attention of the Elder Gods.

Still, Sean has been offered the chance to study the occult with a proper teacher and maybe gain a handle on his tempestuous callings. And it seems like a safe choice—overseen by Helen Arkwright, a friend of Sean’s father and heir to an ancient order of much power, founded to protect New England from that which lurks in the coastline’s unseen depths. But will learning theory be enough, when there is a much greater magical secret hidden in Helen’s vaulted library?

Accompanied by his best friend, Eddy, and their enigmatic new friend, Daniel, Sean wades out deeper into mystical legend and shadow. With hints and secrets buried long in family lore, they turn to the suspicious Reverend Orne once more for assistance. But as Sean deepens his understanding of his power, the darkness is waking.
