As the Dagger, Alex Stone hunted down supernatural threats on covert ops team, Night Command. After the capture of a particularly bad-ass vampire, Tristan Ambrose, Alex gets out of the game. In the years following her departure, Alex started a hot new clothing line and moved on with her life. She was happy pretending the supernatural didn't exist, but, with Tristan's escape, she's pulled back into the game. 
Alex is hired to continue guarding the very tempting body of Jason Stavros—up-and-coming vampire politico—alongside her new team, The Trackers. Stavros is scheduled to head to an international conference of the supernatural community in Bucharest, and Alex and her new team must keep him safe while investigating new threats, and ghosts from the past.
When the conference is interrupted by betrayal and sabotage, Alex must pull her weakened team together to bring the saboteurs to justice—and get some well-deserved revenge. 
Suddenly, she's not just back in the game, she's all in.

By Blood Sworn is the thrilling, psychological, and sexy sequel to In Her Blood, the first book in The Dagger Chronicles series by Janice Jones.
