Aside from the fact that this is an April Fool's Day product, there is a certain perversity to the product. An awful lot of work has gone into designing the book, and the 0.99c price tag is worth it just based on the strong novelty factor.
This is essentially a 'Choose Your Own Adventure' story for Vampire; the Masquerade, hence my use of the word 'perverse'. The very idea of shoehorning the Storyteller System into this type of format is the antithesis of what White Wolf stands for, in my opinion. Most basic rulebooks have a similar set-up to demonstrate the type of play experience that you can expect from the system (reminiscent of the old Red Box D&D intro), but this format wouldn't have worked as a serious proposition.
However, you have to read this as a novelty product, and as such it is quirky and enjoyable. And who knows - you might grab some plot points for your next game. Well worth investing less than a dollar and an afternoon of reading.
