I have read some reviews saying that this edition of Keats' poetry is not complete, but it darn well feels like it! Alongside the well-known poems are the ones which I had never even heard of: A Galloway Song, Sharing Eve's Apple, Sonnet to a Cat. (If these are already well-known then I apologise!) As a bonus the book includes detailed notes for each of the poems so you don't have to go and look up all the obscure mythological (mostly Greek) references as there are a lot of them.
And the poetry itself? No adjectives can describe it apart from "beautiful". There are the short sonnets for when you only want to read a quick few and the lengthier ones such as Endymion if you have a bit more time on your hands. Keats was truly the master of the senses, able to create a huge variety of moods for all seasons from the mellowness of autumn to the sweet and fragrant spring. In true Romantic spirit he writes love letters to Nature, to rambling fields of wildflowers and vast rolling hills. The rhythm of the poems give them the flow of a river, a stream running through a forest untouched by human hands.
Read Keats and let yourself be transported to some of the most sensual worlds found in poetry. At such an affordable price you've got no excuse.
