A Rose to the Torch. Into Vermilion, #1

"Leave no blood for the Rose." In a world shaped by the rise and fall of the hemomancers, one seemingly ordinary girl from North Carolina is the key to ending a century-long war-and she wants nothing to do with it. Coral never wanted to be a hemomancer. Why would she? In a world built on the wounds the hemomancers carved in history, being discovered as one is a death sentence. But when a group of hemomancers track her down, she finds herself pulled into the orbit of a war that has raged in secret for a hundred years.
Now, disowned by her family and possessing blood coveted by the villainous Rosarium, Coral has little choice but to accept the aid of the mysterious Orchid Veil and set foot into the world of the hemomancers, a world rife with danger and intrigue. But once there, she quickly discovers that being a hemomancer is even less glamorous than she'd imagined. Torn between two worlds and welcome in neither, her hunt for a place to belong will force her to confront the darkness in her own heart.
Will Coral be able to survive the war being fought over her own blood? And if she does, will she ever be the same as she was before? A dark, brooding urban fantasy about blood magic, human frailty, and revenge.
