For anyone wanting a good introduction to the actual poetry of Sylvia Plath, I would thoroughly recommend this book.
As a teacher I have tried a dozen or so different books over the years. Many give a good insight into the lives of Syvia Plath and Ted Hughes but few actually get to grips with her poetry. Students seem to make more sense of Plath more quickly with this book.
Elaine Connell introduces students to the some of the important issues such as whether Plath was a feminist, how Plath pioneered the use of everyday things such as motherhood and cutting her finger in her poetry.
Although the book is an introductory work it deals with some of the deeper issues surrounding Plath in an interesting and readable manner...
