This is a cute little novella length series. I enjoy the characters, the pizza descriptions and the plots are always interesting and novel. The only reason why I don't rate these books higher is because they read almost like a rough draft. There's a lot of detail about the mundanity of Ellie's life, but very little detail in the plot itself, and the endings are usually very abrupt. Granted, the books aren't very long, but I've read books that achieve the balance between a full plot and novella length so I know it can be done.
Overall, this is a cute series and an enjoyable, quick read but would be so much better with a little work.
