Violet Mackerel's Possible Friend by Anna Branford
Violet Mackerel is moving house - and using her theories to help make friends! Violet Mackerel has just moved house. She doesn't have any friends near the new house, so making one is high on her To Do list. A possible friend is the girl next door, who shares Violet's love of small things. An exchange of small notes (and small gifts!) later, a BIG invitation arrives. Rose is having a birthday party... What better way to turn a POSSIBLE friend into a VERY GOOD friend!
