Braelynn's Birthright--Book 1: Wendigo. Braelynn's Birthright

Imagine a world where the creatures of nightmare are real. This becomes fifteen-year-old Braelynn Hanlon's world once she inherits her birthright in the form of her grandmother's ring and is tricked into putting it on. You see, the women in her family have been cursed, doomed to defend humanity from things that go bump in the night. On the upside, the ring comes with super-healing powers, but it also makes her a magnet for all things supernatural.
Her mother has had years to come to terms with her fate, but Braelynn's about to get a crash course on how to be a hunter of all things paranormal. Her boyfriend, Seth, turns out to be a vampire. When Braelynn vanquishes him, the leader of Seth's gang sends a bugbear to seek revenge. If that's not bad enough, her best friend, Shannon, is a werewolf, and Shannon's girl crush is enchanted. To make matters worse, the school's activist, Winona, is an Ojibwe shaman in training, hot on the trail of a wendigo disguised as a local businessman who is threatening to destroy the local watershed.
Braelynn and her friends agree to help Winona vanquish the wendigo, but will her ring and her new-found powers be enough to keep her safe?
