Waiting for You by Elle Spencer

Lindsay Hall has spent years haunted by memories uncovered during a teenage past-life hypnosis session, especially the woman she believes she once loved. Those memories have followed her into adulthood, affecting her relationships and leaving her unable to completely move on.

Meanwhile, Ren Christopher is taking a quiet break before starting a new life in Paris, determined to avoid romance and drama after a difficult breakup. But when Lindsay meets Ren and immediately faints at the sight of her, both women are drawn into a mysterious connection that suggests their story may have begun long before they ever met.
