The book I want to know about is an early-to-mid-90’s R.L. Stine wannabe type book about a boy who suspects that his new friend is a vampire. There’s a bit about pizza and garlic I know. I want to say the paperback version I had had a yellow spine/layout.
Maybe either My Babysitter is a Vampire by Anne Hodgman or Prisoner of Vampires by Nancy Garden?
These books are right in the ballpark I am talking about, but I don’t think it’s either of them. In the book I submitted, the vampire is the same age as the kid who comes to suspect his friend is a vampire.
Was there a pet lizard that shot blood out of its eyes when scared, that the vampire kid stole?
That… I have no memory of. What’s that from?
You could try Overnight Bite by Carol Ellis. There are vampire kids and garlic pizza.
Not it… don’t think the book was part of a series, and was more early 90s
