In Khaled Hosseini's novel The Kite Runner, Amir and Soraya enjoy a stable, mutually supportive partnership, based on love, honesty, and respect for one another. In A Thousand Splendid Suns, the union which comes closest to this is Hakim's marriage to Fariba. The analogy is a flawed one, since Amir and Soraya's marriage is not tested as severely as Hakim and Fariba's is. Fariba in particular is never the same after the death of her sons, Ahmad and Noor. Nonetheless, Hakim and Fariba at the beginning of the book have a close, loving relationship similar to that of Amir and Soraya. The polar opposite of Amir and Soraya's marriage is clearly that of Rasheed and Mariam, which is violent, abusive, and ends with the wife beating the husband to death with a shovel.
In The Thorn Birds, Luddie and Anne Mueller are the most similar couple to Amir and Soraya. Anne, like Soraya, has suffered and gained wisdom through suffering. The two are strong enough in their marriage to combine in giving help and support to those who need it, such as Meggie in, just as Amir and Soraya help Sohrab. The polar opposites of Amir and Soraya are Luke and Meggie O'Neill. Though Meggie is rather similar to Soraya as an individual, the loveless marriage she endures with the stingy, miserable Luke is entirely unlike the relationship between Soraya and Amir.
