City of Love by L.M. Strauss

She doesn’t belong in her own world. She can’t survive in his.

Lexi Cross just got fired. Again. Neither her Ivy League education nor her copy of Clairvoyance for Dummies has helped with her so-called gift of sight and the blackouts they cause. But while drowning her sorrows during a night out in Philly, she walks through the door of a secret club and steps into an entirely different universe—one with all the answers she’s been seeking… and the stunning, mysterious man who’s been haunting her visions.
Gideon Ashe also lives in Philadelphia—one without cars, computers, or electricity. A world of gas lamps and horse carriages, where technology is run on powers of the mind. It was Gideon’s discovery that opened the gateway between dimensions, but the portal is fast becoming a Pandora’s box he can’t close. With his deepening feelings for Lexi, he’s no longer sure he wants to.
But Lexi’s presence in Gideon’s universe sets off a string of sinister events that could destroy his civilization. Between cross-world kidnappings, and risk of death from being in the wrong dimensions, they’re going to have to fight for their love.
