Everbody likes Mr Mahli, especially his neighbours,nine-year-old Tomos and Alys. When he goes on holiday they look after his garden on Cwmdonkin Drive in Swansea for him. But they are not allowed in his mysteriously empty shed. But the friends soon find out the ordinary-looking shed is far from empty - it is home to an odd, slightly grumpy ghost called Dylan. Dylan soon persuades the children to take him to school with them for a change of scenery - at first he behaves, but then things start to get out of hand.

It's the summer holidays, but for nine-year-old Steve life in his home town is full of hidden menace. There was that trip to the dentist for a start - and that Thing in the crinkle-cut chips freezer compartment...Steve believes he must protect his family from a dangerous, unpredictable world. But he can't solve all the problems on his own. He's just not quite big enough. Then the mysterious Library of Dreams comes calling and things start to get weird. Steve finds himself an unlikely hero on an impossible mission to outwit flesh-eaters and sabretooth tigers and save the human race.
