I've read both books I needed to and won silver. The two books I've read were:

The boy with the magic numbers was a great book so good I gave it a thee out of three. It was all about this boy, Billy. His dad was a gambler who also was a hair dresser who owned a barbers shop. one day he left, leaving a money box. The money box needed battery's, for Billy to find out that those battery's were only sold in new york. One day his dad gave him ticket to go visit him in new york he goes and takes the money box with him.Then some thing magical happens...
One day the Fat Fairy turns up at Thomas Top's house to grant him a
birthday wish. Tomas wishes to fly. Thomas's ability to fly makes him popular at school, but
brings him trouble too. He is suspended and that makes life at home
with two unhappy parents even worse.
Then the Fat Fairy turns up again, and with help from her and
Thomas's new friend Mr Vinnie, a flying painter and decorator,
everything changes.
I completed both books and won silver. If you wish to sign up for the summer reading challenge you still can at any lewisham library.
