If they are a Christian, they will enjoy it because it investigates moral dilemmas based around themes of justice and vengeance; a real makes-you-think sort of book.
If they are a non Christian - without ever feeling threatened or preached at in any way - by the end, they will understand what the Gospel is.
£9-99 will get you a copy of this excellent novel set in N.Lincs and Sheffield - postage free.
