Say You'll Be Mine — Julia Amante

Isabel Gallegos is only a handshake away from living her dream life. After years of putting everyone else's needs before her own, she's selling her family's vineyard and moving to a quiet cottage on the California coast. But just as she's about to seal the deal, a letter arrives from Argentina with shocking news: Her beloved cousin has died and Isabel is now the sole guardian of three young children.
Still holding on to her dream, Isabel travels to Argentina. There she meets little Julieta, the cherubic baby of the family; eight-year-old Adelmo, as hot-tempered as his sister is sweet; and ten-year-old Sandra, whose heart-shaped face and quiet confidence remind Isabel so much of her late cousin. She tells herself to let the children go, to leave them in the care of their grandmother or perhaps their long-lost uncle who abruptly reappears. Or should she listen to her ex-husband, who is suddenly at her side, urging her to give the children--and him--a chance?

If she's willing to take a risk, three tiny strangers just might change Isabel's life in ways she's never imagined.
