I downloaded the ebook version of this text for a literature exam. I have previously read some of Behn's works, and this is a great little collection. There were one or two typos, but those were minor and no more than what you find even in print editions of books (sadly). The ebook is clean, easy to navigate, and overall a good piece of work.
As far as the book itself goes: This text contains Behn's two proto-novels (Oroonoko and The Fair Jilt), some of her love letters, a small collection of poems--some of which come from her plays--and the plays The Rover and The Widow Ranter. The selected works are different enough that readers are bound to like at least one.
