Ever since the day that changed Oren's life, he's spent his nights wondering if he made a mistake--he can't help but relive the nightmare of Sage gasping for her life. But now that he's made the decision to let her in, how can he risk her becoming a target if anyone were to know she is his weakness? Meanwhile, a petty grievance between witches and werewolves in the Jura Mountains is rising into something much more dangerous. They've requested Arcanum assistance, and Sage has been assigned to the impossible task. But with the shame and embarrassment of her past crushing down on her, she has more to prove now than ever. And Oren refuses to let her go alone. The job seems tame enough at first, but neither expects the darkness that lies ahead: traces of old magic, tortured lost souls, and a rising fog that kills everything it touches. In the captivating sequel filled with twists, turns, and treachery, All the Lost Souls leaves no stone left unturned as Sage and Oren weave their way through new secrets and an even greater mystery that will put everything they've worked for to the test.
