Falling Apart

'I'm sorry, but I don't want to live any longer. It's nothing to do with what you said, Dad, I'd made up my mind to do this ages ago. Mum, maybe it will help to think of your twins together again. 
Jan, I'm leaving you my blue cashmere sweater and all my books, even though they mostly belonged to you in the first place.
Louise, you can have my diamanté brooch and all my make up and any clothes you want. I'd like Carly to have my toy dog. 
Goodbye. 
Love from Tina.' 
 
Tina is fifteen and having a miserable time at home since her twin brother died. She falls in love for the first time. Simon is from a private school and not part of Tina's world. They don't have much in common, but Tina convinces herself she's in love. When Simon ends it with her, Tina's world falls apart.
First published in 1989 and long out of print, Falling Apart is an honest and thought-provoking story written by one of the world's most popular writers. Jacqueline Wilson captures the voices of teenagers perfectly in this engrossing novel about couples and families, and what can happen when it all goes wrong.
