All four books in the Anubis' Warriors series.
Embraced by a Warrior
As a warrior of Anubis, Darius always believed he was destined to be alone. After eight hundred years, he begins to question what he has always known. He finds a woman who stirs not only his desire but his heart as well.
Her Eternal Warrior
Protecting mortals from the evil preying upon them is Tor's number one job. His dying pledge to serve the Egyptian god Anubis gave him immortality and a life of solitude as a jackal shifter—for thousands of years. All that changes when he saves a young woman from being attacked.
Jaxon never wanted to tie himself down to a single woman, not even when he was mortal. When a sexy temptress collides with him on the street, dumping her coffee all over his chest, he sees the opportunity for another installment of his modus operandi—seduce, bed, and then leave.
A Warrior to Love
A warrior of Anubis since 1920, Konner finds the loneliness of his life getting to him. The sexy damsel in distress stirs passions long buried. He must have her—in his life and in his bed. She's everything he's ever wanted in his long existence, but the nature of who he is could end this love affair before he has a chance at forever.
