'Bo'′s back ... in another crazy adventure of Heroes, dinosaurs and the most fearsome weapon in the universes ... the zombie sausage.
'Boojum Bark, werewolf puppy and would-be-Hero, is about to do what no other Hero has done before - go into the scariest universe of them all, the Ghastly Otherwhen, rescue his mum and come back alive. And he'll need help from his friends: mysterious Yesterday, gorgeous Princess Princess Sunbeam Caresse of Pewké, Mug the down-to-earth zombie, and Squeak the warrior mouse. But the Ghastly Otherwhen isn't what Boo expects! And his friends start acting strangely, too ...
'What is the bond between Yesterday and her dinosaurs? And why won't she let Boo rescue her from slavery? Can Mug really be as dumb as he looks, or is it a clever zombie disguise? And could Princess Princess be an actual Hero underneath her cowardly exterior?
'The bogeys are scarier - and the food is grosser than ever - it's Jackie French at her hilarious best!' (From the publisher's website.)
