Echo and the Vampire CEO

Forced by her adoptive parents, Echo marries Nikola, the reclusive founder of the Venture Group, simply because she's seen as a "blood bag" for her sister's transfusions. Expecting an "old man," she's stunned to find Nikola young and kind—save for his strict rule against her touching the coffin in his bedroom. When a bloodstain on Echo's body awakens Nikola's vampire nature, she's plunged into a world of forbidden passion and peril. As secrets unfurl, Echo realizes that her marriage to Nikola is not just a matter of convenience but a dangerous entanglement that will test her courage and draw her deeper into his mysterious, vampire - filled world.
