Great Escapes is probably my favorite book out of the Mates, Dates series. The book covers some quite sensitive subjects, such as sex and teenage love, very well, whilst still keeping it relate-able to the people reading the books.
Great Escapes has also got very good character plot and development.
It is narrated by Lucy, who is the 'younger' one of the group. She is considered 'a late bloomer', as she is much smaller and less developed than Tj, Izzy and Nesta. However, she seems to be the first of the group to deal with the topic of sex and, you could argue, is the first to have to 'grow up', out of the four girls.
As a summary, Great Escapes is a very well written and developed book, and I would strongly recommend it to anyone around the ages of 14 or 15 who is still quite conscious or in the dark about growing up.
