We only made it three choices into this book before it ended. There were a lot of pages of reading between each decision which wasn't the most fun but at least it actually involved Vampire Invaders. (The last book we read was about Ninja, we made 6 choices and never saw one damn ninja.) Our boys thought it was fun to put themselves in the book, so Cliff (5) said he was the vampire expert and Dean (3) said he was the Vampire.
We let them take turns making the choices. Cliff chose to go to New Orleans to find the vampire in the house. Dean said Cliff should bring the SWAT team in with him. Cliff said the SWAT team should shoot the piano (this made Dean cry). **Spoiler Alert** The Vampire's not in the piano, and everybody gets mad at you for shooting it and you get fired and the vampire is happy at the end. So out three year old was happy at the end, and our five year old said he should get to pick the next book. Can't wait.
