Every year, for the past 13 years, Peter and Susan have gone to Lea-on-Sea for their holidays and stayed at the Hotel Vista. However, this year, things start to go wrong as a strange man pretends to be Peter. Who is he? What does he want? And is he friendly or dangerous? "Penguin Readers" is a series of simplified novels, film novelizations and original titles that introduce students at all levels to the pleasures of reading in English. Originally designed for teaching English as a foreign language, the series' combination of high interest level and low reading age makes it suitable for both English-speaking teenagers with limited reading skills and students of English as a second language. Many titles in the series also provide access to the pre-20th century literature strands of the National Curriculum English Orders. "Penguin Readers" are graded at seven levels of difficulty, from "Easystarts" with a 200-word vocabulary, to Level 6 (Advanced) with a 3000-word vocabulary. In addition, titles fall into one of three sub-categories: "Contemporary", "Classics" or "Originals". At the end of each book there is a section of enjoyable exercises focusing on vocabulary building, comprehension, discussion and writing. Some titles in the series are available with an accompanying audio cassette, or in a book and cassette pack. Additionally, selected titles have free accompanying "Penguin Readers Factsheets" which provide stimulating exercise material for students, as well as suggestions for teachers on how to exploit the Readers in class.
