Four Winds by Lisa T. Bergren
Zara Ruiz has never been so happy to have failed at something in her life---trying to return to her own time. In Javier de la Ventura's arms, she knows that 1840 is where she belongs...where she's found true love and family. But when the ranch is viciously attacked, and she and Javier's little brother are kidnapped, she is no longer certain where her journey might end. Javier de la Ventura is plagued by a sense of responsibility for praying that God would leave Zara in his own Alta California. But when she suffers because of her association with him, he commits to finding a way for her to return to her own time, if she wishes it. His heart longs for her to stay, but his mind tells him she’d be safer in her own era. Battered by the FOUR WINDS, can Zara and Javier find a way to remain together…forever?
