Can Alberta help him unravel the mysteries of the perplexing pineapple?'This is a great little chapter book, and I can see it being wafted under the noses of reluctant readers. Why? The Perplexing Pineapple has charm, wit and a number of intriguing activities tucked inside. This is going to be just right for those who are more 'hands on' learners . With helpful clues, (which are given great explanations at the back), a great glossary and rollicking storyline The Perplexing Pineapple works on many levels.' [mybookcorner.com]
