I'm not sure where I read it, but somewhere along the lines someone told me that the blurb of a book isn't actually meant to help the reader. The single purpose of a blurb is to sell the book. Now some may argue that the blurb tells you what the book is about to convince you to read it, but there's a difference between reading a book, and buying a book.
And the difference is this-take the story of Romeo + Juliet-imagine you've read it and you're recommending it to a friend- you might say
"oh I read this really great book, its actually a play in the Shakespearean style about a boy and a girl from warring families that fall in love....it's very emotional and real and even though there are language barriers, it's still captivating and I really enjoyed it"
Essentially this gives you all the information you need about the story, it's a love story, its by Shakespeare and it's good.
Now if you were to go back and pretend Romeo & Juliet was just coming out I imagine the blurb would read something like this
"Romeo is a young Italian man, living his life, carefree and impetuous, unconcerned with anything but having fun. Until he meets Juliet, a beautiful girl at an elaborate party he and his cousins have snuck into. He falls in love with her on sight, beginning a story of love, feuds and revenge, for unbeknownst to Romeo, Juliet is a Capulet, and Romeo's sworn enemy. In trying to organise their secret marriage, Romeo is banished from the kingdom and Juliet takes a drug to make her look dead so they can be together forever. Romeo, inconsolable, kills himself upon her body in the tomb just as she awakes.
A tale of lust, revenge and star crossed lovers, Romeo and Juliet is a timeless story"
And blah blah blah. (give me a break its my first blurb I've ever written).
I have a rule, once you start to read the book, never read the blurb. Because it ALWAYS gives away the story. And it drives me crazy!
Wicker, particularly, I think has a terrible blurb. Talk about condensing the story! It also has this rambling quality "imagine this-and now this-now that" ridiculous.
