Enchiridion

The first novel of the Shadow Speaker series.

After five years of serving as an assassin in the ancient Order of Venir, Saevio is nearing the end of her contract. But after coming dangerously close to failing the Order, and with the Order's ties with the Merchant Guild that dominates the southern continent of Omassin now strained due to her mistake, she risks facing the consequences. Five years in the mortal realm studying humanity will need to be enough if she is to redeem her place in the Order and keep from failing her bargain with the Lord of Assassins.

But just when she has nearly achieved her goal calamity strikes.
Another visitor from her home arrives in the mortal realm, wreaking chaos and destruction, searching for the one who escaped the divide between worlds. Saevio must find answers regarding his arrival, soon, or risk losing the anonymity she has worked so hard to claim, the past she has tried so hard to forget. The mortal realm had been isolated for a reason, and it should have been impossible for another to arrive. But as the danger grows, and enemies close in, one question remains:

How long can she pretend to be human?
