The Hunt for Mara Layil

Mara has broken the most sacred mandate of her kind, and even that may not be enough to rescue her brother, Max.From Japan to Thailand to Istanbul, she's being hunted by the vengeful widow of a First Born, along with an elite fighting force whose job it is to bring her to justice, and an enigmatic cloaked man determined to bend her to his will.
Even as the relium in Mara's blood fuels her growing powers, she can't hope to avoid capture, find her parents, and help her brother on her own. An unlikely crew coalesces around Mara - steady Hiroko, an Offspring skilled in the healing arts; Dalmeet, a snarky, neat-freak bound to Mara through an ancient blood curse; and Ethan, a tech-savvy, pattern-obsessed teenager.
Bound by fate, these unlikely friends face the darkest supernatural conflict of all time. Does Mara have any way to avoid becoming the lynchpin of the whole thing? And will they be able to save Max in the middle of it all?
