I debated for a bit about buying this product. I couldn't tell if this was a compilation or not. I'd really encourage the writers to update the summary of this product to explicitly state this is a sampler of their individual products. It doesn't contain the full content. I definitely would have changed my purchase to individual books.
The product as presented could use some polish. The cover is missing from the pdf, and a table of contents wouldn't be remiss. I'd really encourage the writers to get a third party to do some editting. I noticed errors like "heaven" instead of "haven" and "Just dunce!" instead of "Just dance!". I found the different colored pages jilting, but that might be a personal preference. I couldn't tell if they were to color code the different bloodlines or if they were pulled from the separate books that way. Those suggestons aside this book was really well put together. The layout work looked pretty professional. Glancing through it could be mistaken for an official White Wolf product. The concepts for these bloodlines are really neat.
Again this is only a sample of the writers' full works. If you're interested in perusing these bloodlines before investing in the individual books it's a good buy.
