Life hasn't been a bed of roses for Kieran Titan since returning from training in the Black Mountains. His twin sister, Lorna, is forever altered after he almost lost her forever. Her new fiancé is head of a pack of werewolves he's trying to find his part in. Oh, and he witnessed first-hand what happens when you mess with the angeling.

Things aren't about to get any easier.

With an old foe still hungry for revenge, it's clear the Barnes pack isn't in the clear just yet. Pack members are going missing, adding to a growing list of missing creatures.

A rogue pack is out for blood, and they're no longer hiding in the shadows. This time it's personal, and Kieran must support his sister and his new family in any way he can.

But as the pack becomes increasingly fractured, Kieran finds an ally in latest pack member, Ashlie. An underground guardian and Kia's best friend, Ashlie is a firecracker with the attitude to match. She knows what she wants, and she's got her sights set on Kieran.

As tempers rise, so too do the stakes. What will be left of the twin's new-found family when all is said and done?
