Writing book blurbs

A blurb can help sell a books as much as a good title and great cover. Blurbs need to be catchy, succinct, and entice the book browser to want to read your novel. I must confess, sometimes I spend weeks working on five sentences for a blurb, much to my disgust. However, I just found a blog with a perfect description for writing the tricky little critters.  Hope it helps.
