Billy Broccoli is on a mission. He must work out how to help his ghost buddy (aka the Hoove) become more responsible.
And what better way than getting him a pet? There's only one catch - the Hoove scares dogs out of their fur, birds out of their wings, and fish out of their gills. If Billy can't find the perfect pet, how will Hoover ever learn to make the grade.
You can watch a YouTube clip of the authors discussing the Ghost Buddy series here and there are teachers' notes available.

Pay the Debt or lose a pound of flesh...
Dom should not be going to Rome with the rest of the track team. He wasn't good enough. He knows it, Coach knows it. Rashid, who should be going but isn't, knows it. But it seems The Debt has other plans.
Before long, Dom finds himself in Italy on the fourth instalment. He is to find E Lee Marx, the world's greatest treasure hunter, who's become a recluse following the tragic death of his nephew. It will require manipulation and deception, but Dom is fast becoming a master at both. So much so that when he's in Italy, Dom decides to do a little digging of his own. He travels to the very place where The Debt originated.
But the answers Dom gets only lead to more questions. One thing is certain: whatever The Debt wants, they get.

It started with a kidnapping. A shadowy organisation known only as the Vespers snatched seven members of the Cahill family and demanded a series of bizarre ransoms from around the world. Thirteen-year-old Dan Cahill and his older sister, Amy, began a global treasure hunt, determined to bring back whatever Vesper One needed, so long as it kept the hostages safe.
But when they deliver the last ransom, Amy and Dan discover Vesper One's terrifying endgame. The objects he demanded are vital pieces in a Vesper plot that will harm millions of innocent people. Now the two siblings and their friends are in an all-out sprint to stop Vesper One... before the whole world goes BOOM.
