Tainted (Ava Delaney: Lost Souls #1‪)‬

~Best read after the original Ava Delaney series~

The backdrop may be grim, but Dublin city has become the centre of change. And as the humans and supernaturals figure out how to live in each other’s worlds, the person who forced that change has quietly stepped aside for a peaceful life.
Ava Delaney is still trying to adjust to her own altered existence when a tainted nephal turns up on her doorstep, apparently on the run from the monster who changed Ava’s life before she was even born. But she’s not supposed to interfere, even for the lost souls she’s vowed to help.
But as the first vampire leaves death in his wake, and Ava becomes an easy target to blame, she realises she has to take care of business once again. There are more secrets hidden in the shadows, more voices just waiting to be heard, and obedience has never been Ava’s thing.
Only one thing is for certain: for people like Ava Delaney, there’s no such thing as a peaceful life.
