Although I did enjoy this, I almost felt like the lessons to be learned were smacking me in the face. Have teenagers these days lost the ability to read subtlety? 
 The title of this story says it all; Anya has a ghost. She falls into an abandoned well (which is somehow left exposed in a public park for 90 years?) and finds the bones, and ghost, of a young girl. Anya sees the ghost as a new best friend, but it doesn't take long for things to become sinister. 
 I can very much see this book being given to teens by their parents as a poorly masked warning for better behaviour and a healthier self esteem. Fingers crossed that this helps for even one of them.
