The Unwritten Rule is the story of Sara who is in love with a boy whose sweet, sensitive and caring. But he is also her best friend's boyfriend. And that is the unwritten rule; wanting what you can't have, that a girl's boyfriend is off-limits to her friends. 
 Elizabeth Scott is an amazing writer with a real gift for writing teenage angst, I feel. Reading The Unwritten Rule was sort of painful but in a good way, because it's realistic and it really speaks to teenagers. 
 Sara is an extremely likeable teenager. Shy and awkward, she is unsure of herself and when she starts crushing on her best friend's boyfriend, she actually tries her best to stop because she doesn't want to hurt her. On the other hand, I have to say, I can't feel much sympathy for Brianna, Sara's best friend. I thought she deserved some sympathy on account of her home life but the way she acted in the way, well, I'd never! 
 As you might have guessed, The Unwritten Rule doesn't end happily ever after. It's more of a bittersweet ending, but it's still believable and realistic. 
 On the whole, The Unwritten Rule is a poignant story about teenagers making mistakes and how those mistakes can snowball and alter the future entirely. But it's also a story about love and the different kinds of love we have to live with.
