First off, this doesn't seem like a series you need to read in any particular order. Each of the seven books tell the story through one of the grandsons, and the novels overlap each other in time. You'll get more if you read several, especially if you read ones about siblings. Spencer is Bunny's brother, so he gets quick messages about Bunny's task (Ink Me).This was a very fast, middle grade read. The story is gender neutral, which is great. There are elements that will probably attract boys more, and some that will draw girls more. But it was the gangster part of the story line that really kept the story moving along. One thing I liked most was that Spencer seems to be more of an introverted character, and not the stereotypical boy who likes sports and showing off. If you are looking for a contemporary middle grade novel that is not romantic in nature, you should check this out.
