My sister-in-law gave me five Beverly Lewis books, from the "Abram's Daughters" series, for my 13 year old daughter to read at leisure. She really enjoyed Jeanette Oke's Love Comes Softly series and I am wondering if these will be along those lines. Basically I am wondering if these books will be appropriate for her, or are there adult themes that I should be aware of? Any help would be much appreciated
