Firebinders: Fleur - The Firebinders Series, #2

Who can she trust? Fleur Fenwick, a firebinder, is on the run. After her friend is killed, she unearths a secret that can spell life or death for all firebinders, including her brother. When the police get involved, the detective assigned to protect her not only sends her heart racing, but also seems to know the reason why there are forces who want firebinders dead. Cynn Cruor warrior Ewan Blair returns to the city to fulfill a promise he made to a woman-child.
While on patrol with fellow Cynn Cruor Blake Strachan, he encounters a beautiful woman who not only holds her own in a fight with the Scatha Cruor but also sets his blood afire with a desire he never thought possible. Dead bodies start piling up, illuminated manuscripts with hidden clues, and Fleur's brother goes missing. It's a race against time to get firebinders to safety. Through it all, the sensual conflagration between Fleur and Ewan is undeniable. So is the threat to them both.
