By the Billabong (Daughters of the Darling #3)
Annie Seaton

Though initially guarded, she and Miles gradually develop a friendship that sparks an attraction. Her family, however, worries that she's vulnerable, questioning whether she can truly trust Miles. As Tom and Cat unearth the poignant love story of Gilbert and Matilda—forced apart by war and bound by secrets that echoed through generations—Erin finds herself walking a path that mirrors her great-aunt’s. Both women faced impossible choices about trust, truth, and the courage to fight for love.
While Matilda guarded her heart's deepest secret beside the same billabong a century ago, Erin must decide whether to follow her heart—or listen to the doubts that surround her.
But unlike Matilda, who faced her struggles alone, Erin will discover that some family bonds can transcend even time itself..
