All Zeke and Eppie have to do is play with their new neighbours, Tig and Pop, and take care of them at school, and stay out of trouble for just one day. But if they do all that, their mum will buy them a puppy! Only problem is, Tig and Pop are aliens! So staying out of trouble might not be so easy. This four-book collection includes the whole series of Gretel Killeen’s brain-crackingly funny adventures, with Zeke and Eppie as they get dragged into space, save an ice-cream tree from being stolen and journey to the centre of the stomach!
