Infinity: A Bridger's Origin. Bridgers

Infinite worlds. Extreme danger. One fearless woman. Passerina Fowler just wants to be a professional fighter. She has struggled for years to make a name for herself. But then her life abruptly changes when she's discovered by a recruiter from SafeTrek Bridging, a company that transports clients to alternate versions of Earth. With nothing to lose, Passerina accepts a job as a bridger, an elite fighter who protects clients on excursions to alternate worlds.
However, on her first day she witnesses a horrifying event and realizes bridging can be downright deadly. In spite of the risks, she is determined to complete her training program. But she soon realizes the training is more focused on her fears than her strength and endurance. And for good reason-there is much to be feared when bridging to alternate worlds naked and unarmed. Passerina must steadily transform herself into a bridger, with a new name: Infinity.
Infinity grows impatient for the excitement and danger of her first bridging excursion. But when it finally comes, she finds herself in a world of vicious predators, and the danger becomes all too real.
