If you like reading the first 250-word blurbs from your favorite genre, or if you want to know if your work will spark interest in other readers, then check out www.webook.com. You have the opportunity to rank submissions and help move them to the next level, which is submitting an entire chapter. From there, entries can submit partial (first 50 pages) and fulls. Work is also reviewed by participating agents, so what better place to get feedback and possible agent representation!
