The TRUE Meaning of Smekday

This is my first post. I am going to review a book by Adam Rex called The True Meaning of Smekday. This children's Sci-Fi book has the following:
- A girl named Gratuity (or "Tip" to her friends)
- A boy alien named J.Lo.
- A cat named Pig
- A bunch of alien species (eg Boov, Gorg, Long Eared Koobish)
- Freaky nerds who live in Roswell and work as U.F.O.ologists
- Comics here and there
- And waaaaaaaaay more
Beware! This summary could have spoilers! A quick and not too detailed summary of this book is that aliens called the Boov come to earth and relocate the humans to florida. Gratuity drives there instead of taking the Rocketpods, and ends up with a Boov named JLo as a friend. Later on, a second race of aliens called Nimrogs (Gorg) come to earth and now, "Tip" and JLo have to find a way to defeat them.
