The memory thief / Leonie Agnew ; with illustrations by Kieran Rynhart.

Seth has been trapped behind the iron bars of the public gardens for as long as he can remember. By day he's frozen as a statue of a shepherd boy, but as soon as the sun sets he roams the park, ravenously hungry. He is a troll, and the food he seeks is human memories. Then he meets Stella. There's something so different about her - Seth doesn't want her memories. He simply wants to talk to her. But there's someone else in the garden who sees Stella as a threat and a meal. What is Stella trying to forget? What are the memories that Seth is piecing together? And will he ever escape the lonely garden and start truly living?
