Three Little Ghosties by Pippa Goodhart
Three Little Ghosties sit on three posties bragging about how scary they are: one of them terrified a troll, one scared a witch and another spooked a giant. And to prove how scary they are they set off to really frighten some plain old girls and boys ...but they get far more than they bargained for. Ghosts are no match for a little boy in pyjamas! Beautifully illustrated with incredible detail, lots of humour and wonderful characters.
