Best Friends by Jacqueline Wilson - old paperback

Age :9-11

Gemma and Alice were born on the same day and have been devoted best friends ever since. Despite Gemma's larger-than-life personality and Alice's quieter, calmer character, the two are inseparable - until Alice has to move house, all the way to Scotland.

Gemma is utterly distraught, particularly at the thought that Alice might find a new best friend. Is there anything Gem's brothers, or perhaps her grandad, can do to help?
