Love's Sacred Song, Treasures of His Love Series by Mesu Andrews and published by Revell.
Standing in the massive shadow of his famous father, young king Solomon wavers between fear and bravado, wisdom and folly. In the uncertain world of alliances and treachery, Solomon longs for peace and a love that is true and pure--a love that can be his cornerstone.
A shepherdess in the northern city of Shunem, Arielah remembers the first time she laid eyes on Solomon in Jerusalem when she was just seven years old. Since then she has known that it was her destiny to become his bride. When her father, a leader of their tribe, secures a promise from King Solomon to marry Arielah as a treaty bride to help unite the kingdom, it seems her dreams may come true.
