Step back in time to discover how the Crae family got to where they are today. He's a sword in the dark, always finding himself in the right place at the right time. Heath Crae, werewolf prince and enforcer for the pack, knows the right thing to do is to help unseat the usurper king of the demons. It's half his fault that the king has a legendary, feared sword that gives him power over others, after all. Known for his skills on the battlefield and ability to topple kings, Heath is the perfect man for the job. But he'll need a guide to get through the famously inhospitable realm of Demonheim. He longs to bring true peace to his home. Chase is the secret bastard-born son of the usurper king, and he's been walking a dangerous path of undermining his father for the rebel cause for years now. Sick of taking one step forward to take two steps back, he's ready and eager to act as a guide for Heath. But discovering that they're mates changes everything. But war may be too ugly for a newly-mated couple to handle. Bruised and battered by the war around them, Heath and Chase need to discover not only how they work as a couple, but also how they can fit into a changed world. Will they break under pressure, or will they forge a new future together? A M/M mating-bond spicy paranormal romance, Heath is a guaranteed HEA that stands alone. Each book in the series is focused on a different Crae sibling.
