Family and blood.
After 1100 years, these simple words mean everything to Herald. His life has been ruled by keeping his siblings safe, keeping them from becoming prey whilst feeding on the weaker. His failures have been many and measured by those he has lost. People like his twin brother.
There has always been another enemy.
Just who the enemy is comes into question when Herald meets the dangerous, angelic creature he is to guard. Wondering where his true loyalties lie is a dangerous thought. No matter whether he chooses family over the heart, it will mean death.
Only the right choice will ensure the life taken is not his.
