An Alien called, Robert

An alien contacts three children. The alien has crashed into a lough in Donegal Ireland. Its safety craft, that it has lain in for over a thousand years, is surfacing.
Each of the contacted children is intelligent. The boys are lonely. Paul is very overweight. Conor's father is dead. Sarah is a computer genius. Robert unites them by asking them to help him get to the top of Errigal, the highest mountain in Donegal. There his parents are to come from a galaxy billions of miles away for him. But they are stalked by Scoop Smith and other government agencies. The children's midnight mission is the basis of this exciting tale that should be enjoyed by children of all ages.
