Dustbin Baby by Jacqueline Wilson
April knows she was found in a dustbin fourteen years ago as a new-born baby. And now she's fairly happily settled with her foster mother, Marion. But she's desperate to recall what happened in the intervening years, and to see if she can find out where she really came from in the first place. A highly moving but very accessible novel, in Jacqueline Wilson's unique, acclaimed and adored style.
